Unformatted text preview: Respiratory System Review Sheet Reading Assignment: Students should read: Chapter 6 and 7 Section 1: Definitions. Where appropriate, include illustrations and/or a description of what conditions, hormones, enzymes engage the given process, etc. 1. Respiratory System 10. Alveolar Air 18. Venous O2 content 2. Cellular Respiration 11. Fick’s law 19. A-VO2 Δ 3. Pulmonary Respiration 12. Hemoglobin 20. %Hemoglobin saturation 4. Ventilation 13. Oxyhemoglobin 21. O2-HB Dissociation curve 5. Alveoli 14. Deoxyhemoglobin 22. Bohr Effect 6. Gas Exchange 15. Iron Deficiency Anemia 23. Myoglobin 7. PO2 16. Total Oxygen Carrying 24. 2-3 DPG 8. Barometric Pressure Capactiy 25. O2-MB Dissociation curve 9. Ambient Air 17. Arterial O2 content Section 2: Short Answers. Students should be able to answer the following questions: 26. Identify the two places that gas exchange occurs. 27. Summarize/Illustrate how oxygen is transferred from (a) inspired air to pulmonary blood and (B) tissue capillaries to muscle tissue. 28. What is the composition of: a. Ambient air? b. Alveolar air? 29. Given the barometric pressure of 690 mm Hg, compute the PO2 of ambient air and alveolar air. 30. Given the barometric pressure of 500 mm Hg, compute the PO2 of ambient air and alveolar air. 31. What is the PO2 of: c. Ambient air at a barometric pressure of 690? d. Alveolar air at a barometric pressure of 690? 32. Why is PO2 lower in alveolar air than in ambient air? 33. Why does the composition of air change as it travels from outside the body to inside the alveoli (before gas exchange occurs)? 34. Tabulate the PO2 of ambient air, alveolar air, arterial blood (before gas exchange) (assume: for an individual at sea level). Show all of your work. 35. Tabulate the PO2 of ambient air, alveolar air, arterial blood (assume: for an individual at a barometric pressure of 500 mmHg). Show all of your work. 36. What is the primary factor in gas exchange? 37. What will happen to the time required for gas exchange as intensity of exercise increases? 38. Relate the change in pressure difference between: a. Alveoli and blood entering the pulmonary capillary at rest (e.g., higher, lower, the same). b. The alveoli and blood entering the pulmonary capillary during exercise. c. Blood entering the muscle capillary and muscle cell at rest. d. Blood entering the muscle capillary and muscle cell during exercise. 39. What are the two ways that blood carries oxygen in the blood? 40. Explain the importance of oxygen dissolved in the fluid portion of the blood. 41. State: a. How many oxygen molecules can be bound to hemoglobin at any one time, and b. How many ml of oxygen can be carried per 1 gram of hemoglobin. 42. Answer the following with regard to hemoglobin levels: a. Who has higher hemoglobin levels? b. Explain what that means in terms of performance? c. How women’s bodies compensate for lowered hemoglobin levels. 43. Given a hemoglobin count of 16.5 grams of hemoglobin per 100 ml of blood, determine (Show all work): a. the total oxygen carrying capacity of blood, b. arterial oxygen content at rest and during exercise, c. venous oxygen content at rest and during exercise (assume cellular PO2 drops to 35 mmHg), d. a ­vO2 difference at rest and during exercise. 44. Describe the relationship between intensity of exercise and: a. arterial oxygen content b. the venous oxygen content, c. a ­vO2 difference. 45. What is the percent saturation of hemoglobin in: a. the arterial blood at rest and during maximal exercise? b. the venous blood at rest and during maximal exercise? 46. Given a hemoglobin count of 11 grams of hemoglobin per 100 ml of blood, determine (Show all work): a. the total oxygen carrying capacity of blood, b. arterial oxygen content at rest and during exercise, c. venous oxygen content at rest and during exercise (assume cellular PO2 drops to 35 mmHg), d. a ­vO2 difference at rest and during exercise. 47. Describe the relationship between percent saturation of hemoglobin and PO2 in solution. 48. Convince a high school coach why oxygen supplementation on the sidelines during a football game will not improve performance. 49. Describe the bohr effect and discuss the factors that increase O2 unloading to the tissues. 50. Tabulate the PO2 of ambient air, alveolar air, arterial blood, muscle cell, and venous blood, pulmonary capillary (before gas exchange) (assume: for an individual at a barometric pressure of 610 mmHg). Show all of your work. ...
