How would the JG cells respond if blood pressure going into the kidney were TOO HIGH?
Vasoconstriction of the afferent arteriole.
Vasodilation of the afferent arteriole.
How would the JG cells respond if blood pressure going into the kidney were TOO LOW?
Vasoconstriction of the afferent arteriole.
Vasodilation of the afferent arteriole.
