Kidney responds to shock by

Kidney responds to shock by
a) Decreases renal blood flow
b) Increases afferent arteriole resistance
c) GFR remains unaltered
d) Perfusion of kidney increases
Correct Answer - B
Answer: B - Increases afferent arteriole resistance
Kidney utilizes the following mechanisms as a response to
shock:
Release of aldosterone from hypoxic kidney
Release of ADH due to decreased effective circulating blood
volume.
Reduced GFR due to arteriole constriction
Tissue fluid shift into plasma due to lowered hydrostatic pressure
(Hypotension)
