KROK 1 2012 – Question 90 · KROK (Medicine) · Physiology
Atria of an experimental animal were superdistended by blood that resulted in decreased reabsorption of Na+ and water in renal tubules. This can be explained by the influence of the following factor upon kidneys:
- A. Aldosterone
- B. Vasopressin
- C. Angiotensin
- D. Renin
- E. Natriuretic hormone
Hint
Atrial stretch signals excess blood volume; ask whether the kidneys should then conserve or eliminate salt and water, and which circulating factor carries that message.
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.
