Write your answer on the line provided. _________________________19. The human circulatory system consists of the heart, the blood vessels, and the blood. _________________________20. Oxygen-rich blood is pumped by the right of the heart through the lungs. _________________________21. Blood returning to the heart from systemic circulation is laden with carbon dioxide. _________________________22. Valves in the heart ensure that blood moves through the heart in a two-way direction. _________________________23. In the circulatory system, the exchange of nutrients and wastes occurs in the arteries. _________________________24. Red blood cells are produced in the periosteum. Reviewing Skills Structure of the Heart: write the name of each structure 13 14 15 16 Path of Circulation: complete S. & I. Vena Cava Right Ventricle Lungs Left Atrium Aortic Valve Reviewing Terms - Respiratory On the line provided, write the letter of the matching term. Each choice can be used once, more than once, or not at all. _____1. main passageway to the lungs _____2. muscle that controls breathing as it contracts and relaxes _____3. flap of tissue that prevents food from entering the trachea _____4. structure into which air enters after leaving the pharynx _____5. tube through which air travels from the trachea to the lungs a. b. c. d. e. f. g. h. pharynx epiglottis larynx trachea bronchus bronchioles alveolus diaphragm _____6. passageway from the mouth and nose to the rest of the respiratory system _____7. dome-shaped muscle that separates the chest cavity from the abdominal cavity _____8. part of the respiratory system where the vocal cords are located _____9. structure whose common name is the windpipe _____10. small air passageways found inside the lungs _____11. small air sac that is surrounded by a network of capillaries where gas exchange takes place Reviewing Concepts Complete each statement by underlining the correct word or phrase in the parenthesis. 12. The function of the respiratory system is to bring about the exchange of oxygen and (carbon monoxide, carbon dioxide). 13. After they are inhaled, particles are trapped in the mucus layer that coats much of the respiratory system. Then (cilia, alveoli) sweep the particles away from the lungs. 14. During inhalation, the diaphragm (relaxes, contracts). A B C B D 15. The structure labeled A in the diagram above is the (larynx, trachea). 16. Each of the structures labeled B in the diagram leads to (a lung, the heart). 17. The structures labeled C in the diagram finally end in (tiny air sacs, pleural membranes). 18. A network of (intercostal muscles, capillaries) surrounds each of the structures in the diagram labeled D. Reviewing Skills 19. Complete the graphic organizer to show the path that air travels during inhalation. 1 20. Write the name of the labeled structure. 12 2 11 3 10 4 5 9 6 8 7 21. What happens when air enters the alveoli of the lungs?
