Question:

A fall in glomerular filtration rate (GFR) activates:
Adrenal medulla to release aldosterone.
Adrenal medulla to release adrenaline.
Posterior pituitary to release vasopressin.
Juxta glomerular cells to release renin.

Posterior pituitary to release vasopressin.

Adrenal medulla to release adrenaline.

Adrenal medulla to release aldosterone.

Juxta glomerular cells to release renin.

Solution:

A fall in glomerular filtration rate (GFR) activates juxtaglomerular of kidney cells to release renin, which activates the renin-angiotensin-aldosterone system (RAAS), is a signaling pathway responsible for regulating the body's blood pressure. As the blood pressure is regulated the GFR is also regulated.
