Rest and RunChapter1You and a friend take part in a fun run.The starter raises an air horn and starts tocount down three two one. The horngoes off, and everyone starts to run.As you run, you start to breathe faster.Big QuestionWhat happens toyour breathing andheartbeat whenyou run?Breathing consists of inhaling andexhaling. Air moves into your lungs whenVocabularyyou inhale. Air moves out of your lungsbreathe, v. to takeair into the lungsand then to expel itfrom the lungswhen you exhale.As you run, your heart beats faster, too. Theheartbeat is also called a pulse. Each timeyour heart beats, it contracts and pushesblood throughout your body.heartbeat, n. beatcaused by theheart contracting,or squeezing, andpushing bloodthroughout the body1
Your pulse is the rate at which your heart beats. Rate means thenumber of times something occurs in a specific period. Pulse isoften measured by the number of times your heart beats in aminute. Breathing rate and pulse are called vital signs. They areused to measure your health.Word to KnowAs you cross the finish line, you stoprunning. You feel out of breath, and you canfeel your heart pounding in your chest. Bothsensations can happen when you exercise.2Vital refers to thingsrelated to life.
RespirationChapter2At the start of a run, a runner’s breathing isrelaxed and slow. His heartbeats are slow andunnoticed. Once the run is under way, he canfeel his body working hard. He notices he isBig QuestionWhat is respiration?breathing much faster and harder.VocabularyBreathing is the body process of takingin oxygen and getting rid of carbondioxide. When you inhale, air goes intoyour lungs. When you exhale, air leavesyour lungs. Gases transfer back and forthbetween your body and the air in yourlungs. This process is called respiration.What we call air is a mix of different gasesoxygen, n. acolorless, odorlessgas necessary foralmost all lifecarbon dioxide, n.a gas the body givesoff as wasterespiration, n. theexchange of gasesbetween the bodyand airin the atmosphere. Nitrogen makes up thelargest portion of air,Gases That Make Up Airbut oxygen is the gasoxygen (O2)in air that humansneed most. For thehuman body to useenergy from food, itmust take in oxygen.othergasesnitrogen(N2)Oxygen is needed torelease the energycontained in food.3
Respiration is usually involuntary. Yourbody breathes without you having to thinkabout it. For example, when you sleep, youbreathe without controlling your breath.The human body can sense when it needsWord to KnowVoluntary meansdone by choice.Involuntary meansdone withoutchoice.more oxygen, and respiration increases.Breathing also can be voluntary. You can hold your breath briefly,keeping your respiration rate at zero breaths per minute. Butbefore long, your body senses the need for oxygen. It forces youto breathe again.Respiration rate changes with activity level. When a girl walks tothe bus stop, she might not even notice her pulse and respirationhave sped up. But what if she has to run to the bus? The moreactive she is, the more oxygen her body needs. Her pulse andrespiration rate go up.4
The Respiratory SystemThe respiratory system is all the organsthat function together to enable a personto breathe. Gases move between air andthe respiratory system. The respiratoryVocabularyrespiratorysystem, n. theset of organs thatfunction togetherto move gases intoand out of the bodysystem is described in two parts—theupper and lower respiratory system.Word to KnowFunction means towork for a specificpurpose.Upper Respiratory SystemLower Respiratory Systemnosesinustracheathroatlungsvoice boxdiaphragm5
Upper Respiratory SystemParts of the upper respiratory system include the nose, sinus,throat, and voice box.Air enters the bodythrough the nose. Littlehairs inside the nosetrap dust and dirt.The sinus producesmucus. Mucus is asticky fluid. It traps dirtand dust.When the air travelsthrough the mouth andthroat, fluids there alsotrap dust and dirt.Before leaving the upperrespiratory system,the air passes throughthe voice box. The tophalf of the voice box isconsidered the end ofthe upper respiratorysystem.6
Lower Respiratory SystemParts of the lower respiratory systeminclude the voice box, trachea, lungs, anddiaphragm.Word to KnowA structure is a partof something thatis organized for aspecific purpose.Air continues past thebottom of the voice box,where it connects to thetrachea.Air flows down thetrachea. The trachea isalso called the windpipe.The lungs are organsthat fill with air.Structures in the lungsremove oxygen from theinhaled air.The diaphragm is amuscle below the lungs.When the diaphragmcontracts, air is pulledinto the lungs. When thediaphragm relaxes, air ispressed out of the lungs.7
Protecting the Respiratory SystemThe lungs are soft organs. Theribs protect the lungs from injury.Ribs form a cage to enclosethe lungs. The ribs also providestructure that the diaphragmattaches to.You can help keep yourrespiratory system healthy bynot inhaling anything but cleanair. You can’t always see harmfulthings you may be breathing in,though. Have you ever sneezedin a dusty room? A sneeze isone way that your respiratorysystem protects itself. Irritationin your nose triggers the suddenresponse. Breath leaves forcefullythrough your nose, blowing outmucus and irritants.A runny nose is another sign of irritation or infection in yourupper respiratory system. Irritation in your throat might also causea cough. A deep cough from your chest is your body’s way ofclearing harmful material from your lower respiratory system.Wearing masks in places with a lot of dust, dirt, or germs can helpreduce the amount of particles that people inhale.8
A Closer Look atLungs and BreathingChapter3When you breathe in, your lungs inflatewith air. But lungs are not empty poucheslike balloons. Lungs are complex organs.They are made up of many smallerstructures.Big QuestionWhat are the partsinside lungs, andhow do they work?After passing through the trachea, airenters structures called bronchial tubes. A bronchial tube,or bronchus, branches into each lung. Each tube branchesthroughout the lung into smaller tubes. Air warms as it movesthrough the bronchi. Fluids in the bronchi clean dust from the air.The final, smallest tubes that air moves into are called bronchioles.At the end of each bronchiole is a sac called an alveolus. In thealveoli, air in the lungs and blood exchange gases.Word to KnowExchange means totrade, or give onething and receiveanother.9
Exchanging Gases in the LungsAlveoli are tiny sacs that function to move gases into and out ofthe body’s blood. Each alveolus processes a very small amount ofgas with each breath. But there are about 600 million alveoli in thelungs. That is a lot of gas that is exchanged with each breath.Inside the alveoli, oxygen enters the blood, and carbon dioxideleaves the blood. Very tiny blood vessels wrap around the alveoli.Some vessels carry blood picking up fresh oxygen. Other vesselscarry blood getting rid of carbon dioxide.alveoliblood vessels10
Blood flows continuously through the blood vessels that surroundalveoli. As blood passes an alveolus, oxygen moves through thealveolus wall into the blood. Carbon dioxide moves out from theblood and into the sacs. As air leaves the alveoli, it carries thecarbon dioxide away. When people exhale, they are breathing outthe excess carbon dioxide.movement of airalveolus wallblood vessel wallbloodcarbondioxide outoxygen in11
Factors Can Affect BreathingActivity level changes breathing rate. Kids normally breathe at arate of 18 to 30 breaths per minute. Adult athlete runners learn tovoluntarily control their respiration rate. When running, they try tobreathe between 30 and 45 breaths per minute.Environmental factorscan affect breathing, too.In higher elevations suchas mountain regions, theair contains less oxygenthan in lower regions.Until a body adapts tothe elevation, this makesit harder to breathe.Air temperature also can affect breathing. If the air is too cold,the body will try to heat up by shivering. The added musclemovement causes the breathing rate to increase.Humidity is the amount of water vapor in the air. Air that is veryhumid contains a lot of water in gas form and can also carry a lotof dust. Very humid airis harder to breathe.Nerves in the lungssense high amountsof water in the air.They tighten the airpassages in the lungs.12
Air Quality and BreathingPoor air quality affects breathing. Pollutant particles can get intolungs and block the tiniest air passages. Inhaled chemicals cancause irritation of sensitive lung tissue. Irritation can cause fluids inthe air passages to build up. The built-up fluid limits the flow of air.Exhaust from many factories and machines contains pollutantparticles. Some types of power plants release particles into the air.Smoke and ash from fires are also harmful substances for lungs.13
Areas that are crowded with a lot of people, factories, and vehiclestend to have poorer air quality. But natural areas full of treesand flowers also produce pollens that can irritate the respiratorysystem. Even a home that does not have good circulation of freshair can have poor air quality.Breathing poor air can have a bad effecton your body. Some signs that youare breathing poor air include drynessor irritation of the nose or throat,headaches, tiredness, and shortness ofbreath. Other signs include dizziness,coughing and sneezing, and a stuffy orrunny nose.14
CirculationChapter4At the start of a run, not only does arunner breathe easily, but her heartbeatis slow. Once the run is underway, she canfeel her body working hard. She can feelBig QuestionWhat is circulation?her legs and lungs working much harder.What she may not notice is her heartVocabularybeating much faster and blood circulatingblood, n. a bodyfluid that movesmaterials throughoutthe bodythrough her body.As you breathe, blood moves past alveoliin the lungs. The blood picks up oxygenand drops off carbon dioxide. The processcirculation, n. theprocess of movingblood throughoutparts of the bodyof transporting blood around the body iscalled circulation.Word to KnowAs blood circulates through the body,materials that are vital to life aretransported to all parts of the body. TheTo transportsomething meansto move it from oneplace to another.blood carries oxygen, sugar, and othernutrients to where theyare needed. Circulatingblood also removeswaste products likecarbon dioxide.15
The Circulatory SystemThe circulatory system is all the organs and tissues that functiontogether to move blood throughout the body. The circulatorysystem is made up of the heart, blood vessels, and blood. Bloodmoves continuously throughout the body.The heart isthe pump thatpushes bloodthroughout thebody.Vocabularycirculatory system,n. the organ systemthat moves bloodthroughout thebodyheart, n. themuscular organthat pumps bloodthrough thecirculatory systemblood vessel, n.tubelike structure inthe body throughwhich blood flowsBlood vessels are the tubelike structures through whichblood flows.16
The function of the circulatory system is to move importantmaterials to and from cells. The important materials includegases, nutrients, and other chemicals. These materials are carriedin blood.Veins and arteries are different types of blood vessels. Veins carryblood that is low in oxygen to the heart. Arteries carry blood thatis high in oxygen away from the heart.Materials are exchanged between body cells and blood throughother tiny blood vessels called capillaries. Capillaries releasesubstances needed by cells. Capillaries also pick up waste productsto transport and be released elsewhere.arteryveincapillariesBlood that contains more oxygen is brighter red than blood withless oxygen. That is why pictures usually show veins and arteriesin different colors. Many pictures show arteries in blue. However,blood that has less oxygen is not really blue. It is just darker red.17
Changes in CirculationEach time the heart beats, it increasesVocabularypressure in the circulatory system. Atpulse, n. thedetectable surge inpressure as bloodmoves through anarterycertain places in your wrist and neck,arteries are close enough to the surfacethat you can see or feel this surge ofpressure. This repeating surge of pressureoccurs at the same rate as your heart beats. It is your pulse.When you are active, your body needs more oxygen. Your pulsespeeds up. Blood moves more quickly through the circulatorysystem. When you are still, your body needs less oxygen.Your pulse slows down. Blood moves less quickly through thecirculatory system.012501250125012518more activeless activehigh respiration ratelow respiration ratehigh pulselow pulse
There are many other reasons a person’s pulse can increase ordecrease.Temperature affects pulse. The body tries to stay at a steadytemperature. If the air temperature is too hot or too cold, the heartbeats faster. The increased blood flow works to either warm orcool the body relative to the air temperature.Humidity affects pulse. Thetubes in the lungs narrowwhen too much water inthe air is sensed. Less airenters the lungs throughthe narrower tubes, and theheart beats faster to movethe same amount of oxygen.Emotions affect pulse. Ifsomeone is happy or scared,their pulse increases. Being upset can also speed up the pulse.Frequent exercise strengthens the heart. A stronger heart movesblood through the body more easily. Drink plenty of water withexercise, though. As you lose water, blood becomes thicker, andthe heart then has to work harder to move that blood.19
Blood Pressure and HealthPulsing blood generates pressure in bloodvessels. Blood pressure is a vital sign.Healthy blood pressure measurementsdepend on a person’s age. Blood pressureWord to KnowPressure meansa pushing forceexerted in everydirection.can be higher or lower than normal, too.Blood pressure that is too low is harmful to a person’s health.Blood flowing through the alveoli has trouble picking up anddropping off gases, so a person with low blood pressure can feelshort of breath. Since the heart doesn’t get enough oxygen, thepulse can be rapid and weak.Blood pressure that is too high is harmful to health, too. Highblood pressure damages capillaries and arteries, causing themto harden. Hard capillaries can make it difficult for neededsubstances to move through the body. Hardened arteries can leadto a heart attack, a very serious health emergency.20
A Closer Look at theHeartChapter5With exercise like running, you can start tofeel the muscles in your legs get tired. Butthere is one muscle that might be workingharder than any other muscle in yourbody. That is the heart.Big QuestionWhat are the partsthat make up theheart, and how dothey work?A heartbeat is a quick series of musclecontractions. This repeating actionnever stops during your entire life. Eachheartbeat pushes a small amount of bloodthrough the circulatory system.The heart includes four chambersand some major blood vessels. As thechambers squeeze, blood is pushedthrough the chambers and vessels in aVocabularyatrium, n. upperchamber in theheart from whichblood moves to theventricleventricle, n. mainchamber in theheart that pumpsblood to the arteriesspecific order.left atriumleft ventricleright atriumright ventricle21
Blood’s Path Through the HeartCirculating through the body, blood follows a specific path by1. entering the heart,2. taking a short trip through the lungs,3. reentering the heart, and4. getting pushed back out into the rest of the body again.Valves in the heart allow blood to flow only in one direction. Theykeep blood from flowing backward.Blood Enters the HeartThe vena cavaare two majorblood vesselsthat carry bloodinto the heart.The blood enters the first heartchamber, called the right atrium. Thisblood is low in oxygen and high incarbon dioxide.22

A Closer Look atBloodChapter6Blood is made up of different cells and tinycell-like structures. Each component has adifferent function.

All these components float in a fluidcalled plasma.white blood cells,n. blood cells thatcontain structuresthat fight infectionsplasma, n. the clearfluid part of blood25
The Clotting Characteristic of BloodSuppose you get a paper cut on your finger. It stings and starts tobleed. You can’t see any blood vessels, but the blood coming fromthe paper cut is leaking from damaged blood vessels in your skinthat are too tiny to see. In a few minutes, the bleeding stops.An important feature of blood is its ability to clot. When a bloodvessel gets damaged, platelets start to group together at thedamaged area. The platelets thicken the blood and reduce its flow.Plasma contains substances called clotting factors. Clotting factorsbind to the platelets. They form a net that strengthens the clot. Thethick, clotting blood material plugs the hole in the blood vessel.You can see blood clotting happen if you get a minor scrape onyour skin. After a short time, the bleeding stops. You are left with ascab of the clotted blood.The scab dries out. Iteventually falls off whenthe injured skin beneathit heals.When you have a bruise,that is a place whereblood has leaked out ofbroken blood vessels intothe surrounding tissue.26
Blood TypesBlood differs among people. Blood is classified into four differentbasic types—A, B, AB, and O. Everyone’s blood is just one ofthese types.Knowing a person’s blood type is importantif they need a blood transfusion. If a personreceives a transfusion of the wrong bloodtype, the blood in their body will attack thenew blood and make them sick.Most blood for a transfusion comes from aWord to KnowBlood transfusionis the injection ofnew blood into thecirculatory systemof a person whoneeds more bloodbecause of illnessor injury.donor, another person. Blood donation isan important way in which people can help others. Healthy peoplecan donate their blood so there is a supply for people who mightneed it.27
Filtering BloodOne function of blood is to help remove waste products from thebody. Circulating blood picks up waste from cells and transports itaway. The human body has two organs that filter solid waste outof the blood. They are the spleen and the liver.Blood cells last about 120 days. After that, they are worn outand must be removed. The spleen is the organ that functions toremove old blood cells. Over time, blood cells can change shape.Being the wrong shape can affect how well the blood cell works.As blood flows through the spleen, it passes small structuressimilar to screens on a window. If a blood cell is the wrong size orshape, it is filtered out.When blood goes through the liver, it gets filtered for harmfulsubstances. Drugs and other toxic substances are caught by theliver. The materials are then moved out of the body in urine andfeces by other body systems.28
Wellness of the Heartand LungsChapter7People have in common the same bodyparts, but people’s body parts are notidentical. Everyone’s body is unique. Theirparts and systems do not all functionidentically or perfectly.Big QuestionHow can wemaintain healthyrespiratory andcirculatory systems?In some cases, things people do canimprove the functions of their bodies. For example, the morefrequently you run, the longer you are able to run at a time. Themore often you do push-ups, the more push-ups you can do.In other cases, the functions of organs or systems cannot beimproved. For example, the lung condition asthma cannot befully cured. Medications can treat the asthma and make breathingeasier temporarily. But there isn’t a permanent cure that fixes thelung condition.In still other cases,things people do canmake the conditionsof their bodiesworse. For example,cigarette smokingcauses terribledamage to the lungs.It is harmful to manyother body parts, too.29
LifestyleEvery day, you eat a different combinationof foods. You participate in a differentcombination of activities. The things youdo and eat combine overall to make upyour lifestyle.With time, your lifestyle affects yourhealth. Lifestyle is not the only factor thatdetermines health. People are born withmany health factors that they cannot changeVocabularyhealth, n. thedegree of wellnessof the bodyexercise, n. activitythat requiresphysical effort, doneto improve healthdiet, n. thecombination offoods a personconsumesor control. However, lifestyle can determinehow long a person lives.The body needs healthful food and regular exercise to stayhealthy and fit. Exercise is physical effort that makes you workhard until you feel tired from it.People can make individual decisions about what they eat and howmuch they exercise. But many people that live in the same area tend toadopt similar diet and exercise patterns. The lifestyle factors that peoplebecome used to seem to have a lot to do with where people live.30
Living in a Blue ZoneScientists study aging to try to figure out how people can stay welland live longer. Researchers have noticed that people in five areasof the world lived the longest. The populations in these regionshave a few things in common: More people live to be 100 years old than in other regions. People there suffer from fewer diseases from which people die. Many of people’s years are spent in good health. They stayhealthier into older age.Loma LindaCaliforniaNicoyaCosta 0 milesResearchers have called these regions, where more people sharefavorable health, Blue Zones. By studying lifestyles of people inBlue Zones, others can learn how to live longer, healthier lives.31
Lifestyle and the Circulatory SystemPeople in the Blue Zones share somecommon habits that especially supportgood health of the circulatory system.People with good cardiovascular healthtend to eat foods that have little addedWord to KnowCardiovascularmeans relating tothe heart and bloodvessels.sugar and fat. The circulatory system is veryaffected by diet. Over time, added sugar and fat in the diet can beharmful to the heart and blood vessels.Fat is an essential part of the human diet. Fat provides energyand some needed nutrients. However, too much fat or the wrongkind of fat in a diet can lead to fatty deposits in blood vessels.Fatty deposits reduce the amount of blood that can flow throughthe vessel. In arteries, this means less oxygen-carrying bloodgets to where it isneeded. Over time,too little oxygen tothe heart can lead toa heart attack.Too much added sugarin the diet causesweight gain. Excessbody weight strainsthe heart. Excess sugaralso contributes toheart disease.32
People in the Blue Zones tend to live active lives. They spend a lotof their day moving around. Exercise is vital to the health of thecirculatory system. Exercise makes the heart muscle stronger. Overtime, the same exercises get easier because the heart gets better atmoving blood through the body to meet the needs of the exercise.Living a more active lifestyle, like the people in the Blue Zones,means the heart and circulatory system function more efficiently.People in Blue Zone regions also have habits of managing stresswith the help of family and friends. Stress releases chemicals in thebody that speed up the pulse and increase blood pressure. Highblood pressure over time damages blood vessels. Having peoplearound to help deal with difficult events helps reduce stress.33
Lifestyle and the Respiratory SystemYour body needs a clean respiratory system to get oxygen to theheart and throughout the body. The respiratory system is severelydamaged by smoking. Smoking injures lung tissue and causesmultiple types of cancer, especially lung cancer. Fewer people inBlue Zones smoke than in other regions.Smoking or vaping introduces pollutants into the lungs. Therespiratory system has ways to trap pollutants that get into thesystem, but it cannot remove all the pollutants. Over time, thesepollutants cause damage to the lungs that cannot be repairedby the body.Some pollutants get into the alveoli and never exit, so they plugup the alveoli. Inhaled chemicals from smoking can inflame thealveoli, making them swell up. Over time,this can lead to holes in the alveoli. Thisleads to a disease called emphysema,which causes a shortness of breath.34Word to KnowCancer is a diseasethat causes tissuesof the body to growwithout control.
Helpful TechnologyChapter8Improved lifestyle does not improve allrespiratory and circulatory problems. Notall respiratory and circulatory disordersrelate to lifestyle.Asthma is a respiratory condition in whichairways narrow and produce more mucus.Big QuestionHow can scienceand technologyhelp the respiratoryand circulatorysystems?Narrow airways mean less oxygen can getinto and out of the lungs. Too much mucus can also block air frommoving through the lungs.Cystic fibrosis is an inherited respiratory disease. It causes theairways to produce too much mucus. The mucus then getstrapped in the alveoli. People with cystic fibrosis are more likely toget lung infections.35
High blood pressure is themost common circulatorydisease. It can be causedby diet and lack of exercise.However, it can also bepassed down throughfamilies. When bloodcirculates under too muchpressure, it can damage blood vessels and capillaries in the body.This can lead to more damage in the heart, kidneys, and brain.Heart murmurs
Inside the alveoli, oxygen enters the blood, and carbon dioxide leaves the blood. Very tiny blood vessels wrap around the alveoli. Some vessels carry blood picking up fresh oxygen. Other vessels carry blood getting rid of carbon dioxide. alveoli blood vessels 1
