Tissue gas exchange ing to Boyle's law, as the volume of a container increases, the pressure Conversely, as the volume of a container decreases, the pressure 3 Air moves into the lungs when a. intrapulmonary pressure is less than atmospheric pressure. b. intrapulmonary pressure is more than atmospheric pressure. c. blood pressure is more than intrapulmonary pressure. d. blood pressure is less than intrapulmonary pressure. 4 Passive expiration is achieved primarily by the a. contraction of the diaphragm and external intercostals. b. decrease in intrapulmonary pressure. C. increase in atmospheric pressure. d. elastic recoil of the langs. 5 Matching: Match the following pulmonary volumes and capacities with their correct definition or description.

B. C. D. Maximum amount of exchangeable and nonexchangeable air in the lungs E. Maximum amount of air that can be inhaled with a forced inspiration F Volume of air remaining in the lungs after forceful expiration G. Maximum amount of exchangeable air that can be ventilated wi forced inspiration and expiration H. Volume of air exchanged with normal, quiet breathing

Explanation / Answer

1. glycolytic catabolism

2. decreases, increases

3. intrapulmonary pressure is less than atmospheric pressure

4. Elastic recoil of the lungs

Total lung capacity

Maximum amount of exchangeable and nonexchangeable air in the lungs

Residual Volume

Volume of air remaining in the lungs after forceful expiration

Functional Residual Capacity

Volume of air in the lungs after a tidal expiration

Vital Capacity

Maximum amount of exchangeable air that can be ventilated with forced expiration and inspiration

Inspiratory Reserve Volume

Volume of air forcibly inspired after tidal inspiration

Tidal Volume

Volume of air exchanged with normal, quiet breathing

Inspiratory Capacity

Maximum amount of air that can be inhaled with a forced inspiration

Expiratory Reserve Volume

Volume of air forcibly expired after tidal expiration

7. IC = TV+IRV = 3450 ml

VC = TV + IRV + ERV = 4550 ml

TLC = TV + IRV + ERV+ RV = 5750 ml
