KROK 1 2015 – Question 43 · KROK (Medicine) · Physiology
Atria of an experimental animal were superdistended with blood, which resulted in decreased reabsorption of Na+ and water in renal tubules. This can be explained by the influence of the following factor on kidneys:
- A. Natriuretic hormone
- B. Vasopressin
- C. Aldosterone
- D. Renin
- E. Angiotensin
Hint
Consider what the heart itself releases when its upper chambers are stretched by excess venous return, and how that signal would change renal handling of salt and water.
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.
