Q. A fall in glomerular filtration rate (GFR) activates
A) juxta glomerular cells to release renin
B) adrenal cortex to release aldosterone
C) adrenal medulla to release adrenaline
D) posterior pituitary to release vasopressin
Explanation
[Solution from source] A fall in GFR is sensed by the juxtaglomerular apparatus, whose JG cells release renin. Renin begins the renin–angiotensin pathway, which only later causes aldosterone release from the adrenal cortex. Answer (1).
