CLOZE EVALUATION PROCEDURE BREATH OF LIFE: OUR RESPIRATORY SYSTEM NAME DIRECTIONS: Select the answer from the four choices given by circling the correct letter. system brings 1. We need food, water, and of course air in order to live. The. oxygen to all parts of our bodies. This body system never stops this vital job because we would not survive without air. 2. The respiratory system consists of specific parts, each with a special job. Air enters through the mouth and nose and is warmed. It moves to the ____, the chamber behind the mouth. This tube leads into two other tubes. 3. After air moves through the pharynx it continues downward. The. directs the air into two separate branches or tubes. These tubes direct air into the lungs. ., or windpipe, 4. There are two branches of the trachea that direct air to the lungs. These tubes are called the ____. They connect each of the two lungs to the windpipe. The exchange of oxygen and carbon dioxide takes place in the lungs. 5. The lungs are filled with tiny air sacs for this exchange of gases. These very tiny sacs are called ____ and are surrounded by blood vessels. It is here that the actual exchange of oxygen and carbon dioxide takes place. 1. (A) circulatory (B) respiratory (C) digestive (D) muscular 2. (A) larynx (B) epiglottis (C) pharynx (D) bronchi 3. (A) bronchi (B) larynx (C) alveoli (D) trachea 4. (A) bronchi (B) alveoli (C) trachea (D) pharynx 5. (A) alveoli (B)larynx (C) bronchi (D) pharynx 6. (A) arteries 6. The tiny blood vessels surrounding the alveoli are essential for transferring these two gases. These blood vessels, called ____, are the smallest of all blood vessels. Red blood cells travel through these tubes and exchange carbon dioxide for oxygen. 7. The breathing process must get the outside air down into the lungs for this exchange process to take place. A very strong muscle called the ____ is located under the rib cage. It works with the lungs and ribs to get air in, and waste gases out, of the lungs. 8. The brain helps regulate the breathing rate. There is a. center in the brain which sends signals to the diaphragm and chest muscles to control the pattern of breathing. This center will make sure that the body has the proper amount of oxygen in the body at all times. 9. The respiratory system can be damaged by various diseases. One such disease called _____ damages the tiny alveoli or air sacs of the lungs. Smoking has been linked with this disease. 10. Other types of disease can damage the lungs very badly. One such disease, called ____, is also linked with smoking. Smoking should be avoided in order to keep our lungs strong and healthy.
