  1. REVIEWRespiratory & Excretory Systems

  2. 1. Which is the correct sequence for the path of oxygen through the respiratory system? • Nasal cavity • Pharynx • Larynx • Trachea • Bronchi • Bronchial Tubes • Bronchioles • Alveoli

  3. 2. The tubes that branch from the trachea are the bronchi 3. The dome shaped muscle below the chest cavity is called the diaphragm 4. During swallowing, the air passage of the pharynx is covered by the epiglottis 5. Alveoli in the lungs are connected to the bronchial tubes by a network of tiny tubes called Bronchioles 6. Explain what happens to gases during gas exchange in the alveoli. Oxygen in alveoli diffuses into capillaries (blood). Carbon dioxide in capillaries (blood) diffuses into alveoli.

  4. 7. Where are the vocal cords located in the body? larynx 8.What prevents the trachea from collapsing? Rings of cartilage 9. Where does the actual exchange of gases occur? Alveoli 10. During gas exchange where does the oxygen and carbon dioxide go? Oxygen diffuses into capillaries while carbon dioxide diffuses out of capillaries into the alveoli. 11. The ______ is a long straight tube that carries air from the back of the throat to the lungs. Trachea

  5. c 13. The order of air movement with in the lungs is best described as • bronchioles to bronchi to alveoli       • bronchi to bronchioles to alveoli • trachea to bronchi to alveoli        • bronchi to alveoli to bronchioles c 12. What structures trap foreign particles and bacteria in the nose and trachea? • pharynx        • epiglottis      • cilia        • trachea

  6. 14. Where are the vocal cords located in the body? Larynx 15. During swallowing, the air passage of the pharynx is covered by the Epiglottis 16. The FIRST branches off the trachea are called bronchi 17. What prevents the trachea from collapsing? rings of cartilage

  7. d 18. Alveoli in the lungs are connected to the bronchi by a network of tiny tubes called • arterioles          • venules        • capillaries           • bronchioles 19. Inside the alveoli, carbon dioxide and oxygen • are transported along microscopic tubules • are exchanged between air and blood   • are produced inside cells        • are exchanged for other gases b

  8. 20. Humans breathe more rapidly during exercise than before it because during exercise the blood contains • an increased level of oxygen • a decreased number of red blood cells • an increased level of carbon dioxide • a decreased amount of hemoglobin 3

  9. 21. What happens to each of the following during inhalation? • Diaphragm • Contracts (pulls down) 22. What happens to each of the following during exhalation? • Diaphragm • Relaxes (moves up)

  10. A 23. Identify the structures labeled in the diagram. A – nasal cavity B – pharynx C – larynx D – trachea E – bronchi F – bronchial tubes G – lung H - diaphragm B C D E F G H

  11. 24. Explain the function of the respiratory system. To carry out gas exchange

  12. A 25. Identify the structure described. • Contain a ciliated mucus membrane • Nasal cavity (A) & trachea (D) b. Voice box • Larynx (C) c. Aids in breathing • Diaphragm (H) d. Throat • Pharynx (B) e. Windpipe • Trachea (D) B C D E F G H

  15. 31. circulatory 32. It came from the lungs.

  16. 33. Oxygen moves from the alveoli (respiratory system) into the capillaries (circulatory) while carbon dioxide moves from the capillaries into the alveoli.

  17. 34.Identify A, B, and D. lung liver kidney

  18. 35. Which organ produces urea? • B. Liver • 36. What is the function of D? • Filter wastes from blood. • Regulate water concentration of blood. • Produce urine • 37. What does organ A excrete? • Carbon dioxide, water vapor • 38. Which organ detoxifies the blood? • kidneys

  19. 39. What are metabolic wastes? Examples? • Wastes from your cells • CO2, H2O, salts, urea

  20. 40. Identify structures A, B, C, and D. Kidney Ureter Urinary bladder Urethra

  21. 41. Which structure produces urine? • A - kidneys 42. What is the path of urine? • Kidneys  ureters  urinary bladder  urethra 43. What stores urine? • Urinary bladder 44. What is the function of D? • To allow urine to pass out of the body

  22. 45. Which human excretory structure aids in the maintenance of normal body temperature? • Skin 46. Why is the skin also an excretory organ? • It excretes water, salt, and urea in the form of perspiration (sweat).
