KROK 1 2018 – Question 81 · KROK (Medicine) · Physiology
Atria of a test animal were superdistended with blood, which resulted in decreased reabsorption of Na+ and water in renal tubules. This can be explained by the effect of the following factor on the kidneys:
- A. Angiotensin
- B. Renin
- C. Aldosterone
- D. Natriuretic hormone
- E. Vasopressin
Hint
Think of the signal released when the atria are overstretched, and whether it promotes loss or retention of sodium 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.
