Name Date Class Enrichment LESSON 1 Hiccups Your diaphragm suddenly contracts and pulls air into your lungs. Your larynx contracts, too, and your vocal cords slam shut. You don’t speak a word. Instead, you . . . hiccup! then they disappear on their own, within a matter of minutes. They are commonly produced by babies and other young animals that eat too quickly or swallow too much air. Even fetuses in the womb hiccup, as shown in ultrasound images. What causes hiccups? Can hiccups be stopped? You might have been told to hold your breath when you have hiccups. Maybe someone suggested breathing into a paper bag for a minute or two. Other remedies for hiccups include drinking a glass of cold water very quickly, swallowing a teaspoon of honey, or being startled. Scientists theorize that these remedies often work because they distract the brain—basically, the brain turns its attention to other, more pressing matters, and the hiccups are forgotten. Holding your breath, for example, increases levels of carbon dioxide in the blood. The brain quickly shifts its focus and works to reduce the amount of carbon dioxide to normal levels. If you would like to avoid hiccups in the first place, health experts recommend that you do not overeat. Eat and drink slowly, and chew your food carefully. Applying Critical-Thinking Skills Directions: Respond to each statement. 1. Compose lyrics to a song that describes the causes and effects of hiccups. 2. Critique this statement: Increased levels of carbon dioxide in the blood stop hiccups. 20 Respiration and Circulation Copyright Glencoe/McGraw-Hill, a division of The McGraw-Hill Companies, Inc. Hiccups are caused by several factors. Irritations to the stomach, the organs in the chest, or the diaphragm play a role. For example, suppose you ate a large meal. Your stomach expands. Gas in the stomach pushes up on the diaphragm. The diaphragm contracts, and the lungs suck in air. The hiccup occurs when the closing vocal cords abruptly stop the movement of air. Hiccups are also associated with swallowing too much air, eating too quickly, drinking too much alcohol, and emotional stress. Hiccups can be caused by more complicated medical problems that affect the central nervous system or the kidneys, among other organs. Hiccups caused by these problems might last for weeks or even months. They can lead to weight loss, insomnia, and exhaustion. Usually, however, hiccups are a minor problem. One erupts every few seconds;
Name Challenge Date Class LESSON 1 The Respiratory System Preventing Lung Diseases According to the American Lung Association, lung disease is the third leading cause of death in the United States. In addition, some 35 million Americans suffer from chronic lung diseases, such as asthma, emphysema, bronchitis, lung cancer, pneumonia, and tuberculosis. Some of the known causes of lung disease include smoking, asbestos, and air pollution. Symptoms of lung disease might include difficulty breathing, shortness of breath, or a persistent cough. Though lung disease cannot be entirely prevented, people can take certain steps to help decrease their chances of lung disease. Educational Multimedia Copyright Glencoe/McGraw-Hill, a division of The McGraw-Hill Companies, Inc. Your school would like to educate students about how to prevent lung diseases. Research the causes and effects of at least two of the diseases mentioned above. Then create a multimedia presentation that includes facts about the diseases and tips on how to prevent them. Share your presentation with the class. Respiration and Circulation 21
Name Date Skill Practice Model Class LESSON 1: 20 minutes How can a model show the physics of breathing? Air flows from areas of higher pressure to areas of lower pressure. This physics principle explains how air gets into and out of your lungs. Can this principle be observed in a model of the lungs? Learn It In science, a model is a representation of how something in the natural world works. A model can be used to explain or predict a natural process. Try It 1. Read and complete a lab safety form. 2. Cut off the bottom one-third of a 1-liter clear, plastic drink bottle. 3. Blow into a small balloon two or three times to stretch it. Have your partner hold on to the bottle. Place the balloon inside the top of the bottle. Stretch the opened end of the balloon over the opening of the bottle. 4. Blow into a large balloon two or three times to stretch it. Tie a knot in the open end of the balloon. Cut off the tip of the opposite end of the balloon with scissors. Stretch the cut end of the balloon over the cut end of the bottle. Secure the balloon to the bottle with duct tape. what happens as you do this several times. Record your observations.
