Step-by-step solution
The regulation of kidney function involves several hormonal feedback mechanisms. A fall in Glomerular Filtration Rate (GFR) activates the Juxtaglomerular (JG) cells to release renin (A matches with IV). Renin converts angiotensinogen in blood to angiotensin I and further to angiotensin II. Angiotensin II is a powerful vasoconstrictor, which increases the glomerular blood pressure and thereby GFR (B matches with II). Angiotensin II also activates the adrenal cortex to release Aldosterone, which causes reabsorption o
