(a) Differentiate clearly between minute ventilation and alveolar ventilation rate. (b) Which provides a more accurate measure of ventilatory efficiency, and why?
Which statement correctly explains why respiration rate elevates with exercise as compared to at rest.
A) oxygen from the blood diffuses into the alveoli for expulsion through exhalation at a faster rate inguinal nodes
B) oxygen from the alveoli diffuses into the capillaries for expulsion through exhalation at a faster rate
C) carbon dioxide from the alveoli diffuses into the capillaries for expulsion through exhalation at a faster rate
D) carbon dioxide from the blood diffuses into the alveoli for expulsion through exhalation at a faster rate
54) Using an individual with a tidal volume of 500mL and a respiration rate of 10 breaths/min.
What would be true when comparing the Minute Ventilation (MV) to the Alveolar Ventilation
Rate?
A) The minute ventilation rate would be greater.
B) The alveolar ventilation rate would be greater.
C) The minute ventilation and alveolar ventilation would be equal.
D) The alveolar ventilation rate would equal 5 liters/minute.
