KROK 1 2018 – Question 67 · KROK (Medicine) · Physiology
Due to prolonged stay in the mountains at the altitude of 3000 m above the sea level, a person developed increased oxygen capacity of blood, which was directly caused by intensified production of:
- A. 2,3-bisphosphoglycerate
- B. Carbaminohemoglobin
- C. Catecholamines
- D. Erythropoietins
- E. Leukopoietins
Hint
Ask which humoral factor couples prolonged low oxygen tension to a larger red-cell mass and thus a higher oxygen capacity.
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.
