KROK 1 2021 – Question 40 · KROK (Medicine) · Physiology
A person has increased pulmonary ventilation because of physical exertion. What indicator of external respiration will be significantly increased compared to the resting state?
- A. Vital lung capacity
- B. Respiratory volume
- C. Total lung capacity
- D. Inspiratory reserve volume
- E. Expiratory reserve volume
Hint
During exercise ventilation rises by deeper and faster breathing. Decide which indices are fixed limits set by lung size and which change with the depth of each breath, bearing in mind that deeper breaths use up reserves.
The answer, the explanation and a note on every option are available once you log in. The account is free: topic tests, a mock exam, mistake review and statistics.
