Question

vasoconstriction of afferent arteriole means​

Answer 1

Answer:

Constriction of the afferent arterioles has two effects: it increases the vascular resistance which reduces renal blood flow (RBF), and it decreases the pressure downstream from the constriction, which reduces the GFR

Answer 2

${\bigstar}$ANSWER${\bigstar}$

• Under conditions of stress, sympathetic nervous activity increases, resulting in the direct vasoconstriction of afferent arterioles (norepinephrine effect) as well as stimulation of the adrenal medulla. ... If blood pressure falls, the sympathetic nerves will also stimulate the release of renin.
