MCB32 Sample Midterm F08 1. Carbon dioxide diffuses from blood into lung in the: A. trachea B. bronchioles C. alveoli D. All of the above 2. Assume that air at the top of Mt Everest contains only the following gases: P O2 = 46 mm Hg P N2 = 180 mm Hg With the assumption that the air at the top of Mt Everest does not contain any water, what is the atmospheric pressure at the top of Mt Everest? Data below is for the next 2 questions. A chamber contains the following: 22% O 2 78% N 2 3. If the total pressure in the chamber is 730 mm Hg, what is the partial pressure of N 2 ? 4. The partial pressure of water at 37 o C is 47 mm Hg. If the chamber described above became saturated with water at 37 o C, what will the partial pressure of O 2 be?

5. The presence of surfactant on the inner surface of the alveoli will: A. increase surface tension B. prevent smaller alveoli from collapsing C. cause smaller alveoli to collapse D. cause the larger alveoli to collapse 6. The residual volume: 7. The partial pressure of CO 2 in the atmosphere just outside of this building is closest to? 8. Most O 2 in the body is:
9. Figure 1 shows two oxygen hemoglobin dissociation curves. The % O 2 saturation and the partial pressure of O 2 in the veins of an individual are described by point A. Which of the following has occurred if % O 2 saturation and the partial pressure of O 2 in the veins shift to the values described by point B. A. plasma pH levels have increased and oxygen consumption has increased B. body temperature has decreased and the plasma oxygen concentration has increased C. the plasma concentration of CO 2 has increased and oxygen consumption has increased D. less O 2 has been unloaded to the tissues 10. In Figure 2 which of the following best shows the change that occurs in the veins when a person is exercising?
