The amount of air exchanged at rest is called O Total lung capacity O Vital capacity O Inspiratory reserve volume O Expiratory reserve volume O Tidal volume

In general, we learned that lung volumes seem not to change in response to exercise training. What was the one sport we do have data showing INCREASED lung volumes after training? O Running O Swimming O Cycling O Cross Country Skiing O Football (Soccer)

What is the pressure of gas within the alveoli at the peak of inspiration, just before expiration, relative to atmospheric pressure? Less than atmospheric pressure Greater than atmospheric pressure O Equal to atmospheric pressure O Unable to be determined

In forming the lung-blood barrier, all of the following are involved EXCEPT: O the basal lamina O Type I alveolar cells O capillary endothelial cells Type II alveolar cells

Normal, resting breaths are called: O Vital capacity O Functional residual capacity O Residual volume O Inspiratory reserve volume O Tidal volume

What is the drive for and control ventilation

During inspiration O The alveolar pressure decreases O The atmospheric pressure increases O The atmospheric pressure decreases O The intrapleural pressure increases O The alveolar pressure increases

Describe the four processes of external respiration.

What is the physicalprocess through which gasexchange is accomplished inthe pulmonary alveoli?

A pilot is flying a commercial, pressurized (760mmHg) airplane at 30,000 feet. If the pilot’s body temperature is normal and the alveolar PO2 is 100 mmHg, which of the following is true? Atrieal PCO2 is 40 mmHgAlveolar PCO2 will be 100 mmHgThe pilot will be polycythemicAlveolar ventilation will be increasedAterial pH will be 7.6
