Correct Answer: the amount of air expelled forcefully and rapidly following the deepest possible breath 2. In obstructive pulmonary diseases, the forced expiratory volume (FEV) after one second is reduced. Your Answer: True 3. A timed forced expiratory volume (FEVT) looks at __________. Your Answer: the percentage of the vital capacity that is exhaled for a specific time during recording of forced vital capacity Breathing rate following hyperventilation is reduced because of the decreased blood levels of carbon dioxide. An increase in respiration is observed with exercise because the blood has increased carbon dioxide levels and decreased oxygen levels Compared to inhaled air, exhaled air has relatively more __________. Your Answer: carbon dioxide 2. Correct Carbonic anhydrase is the enzyme in red blood cells that speeds up the CO2 + H2O (H2CO3) reaction. Your Answer: True 3.
