A fall in glomerular filtration rate (GFR) activates

Options

(a) adrenal cortex to release aldosterone
(b) adrenal medulla to release adrenaline
(c) juxta – glomerular cells to release renin
(d) posterior pituitary to release vasopressin

Correct Answer:

juxta – glomerular cells to release renin

Explanation:

The amount of filtrate fomed by the kidneys per minute is called glomerular filtration rate (GFR). GFR in a healthy individual is approximately 125 ml/minute, i.e., 180 litres per day. A fal in GFR can activate the JG cells to release renin which can stimulate the glomerular blood flow and thereby the GFR back to normal. Renin converts angiotensinogen in blood to angiotensin I and further angiotensin II. Angiotensin II being powerful vasoconstrictor increases the glomerular blood pressure and thereby GFR.
