NEET Biology question

Which of the following is most appropriate regarding kidney function regulation? Stimulation of

(A)Renin-angiotensin mechanism decreases the Glomerular Filtration Rate (GFR) while atrial natriuretic factor increases GFR
(B)Renin-angiotensin mechanism increases GFR while atrial natriuretic factor decreases GFRCorrect
(C)Renin-angiotensin mechanism and atrial natriuretic factor both increase the GFR
(D)Renin-angiotensin mechanism and atrial natriuretic factor both decrease the GFR

Answer: (B)

Solution

The renin-angiotensin mechanism raises blood pressure and blood volume (via vasoconstriction and aldosterone-driven Na+/water retention), thereby increasing GFR,
