KROK 1 2008 – Question 126 · KROK (Medicine) · Physiology
Systemic arterial pressure of an adult dropped from 120/70 to 90/50 mm Hg that led to reflectory vasoconstriction. The vasoconstriction will be maximal in the following organ:
- A. Kidneys
- B. Brain
- C. Bowels
- D. Heart
- E. Adrenals
Hint
Think about which vascular beds the sympathetic system sacrifices first when pressure falls, and which organs have strong local autoregulation that protects their blood flow.
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.
