2020 Phase-2 Excretory Products and their EliminationRenin-angiotensin system and blood pressure regulation Medium Question 19 of 60 in Excretory Products and their Elimination

Select the correct statement:

A Reduction in Glomerular Filtration Rate activates JG cells to release renin.
B Atrial Natriuretic Factor increases the blood pressure.
C Angiotensin II is a powerful vasodilator.
D Counter current pattern of blood flow is not observed in vasa recta.

The answer is A.

Solution

A fall in glomerular filtration rate (GFR) activates the juxtaglomerular (JG) cells to release renin, which triggers the renin-angiotensin-aldosterone pathway to restore GFR and blood pressure.
