Aldosterone stimulates the reabsorption of

Which one of the following four secretions is correctly matched with its source,target,and nature of action?

$ANF$ mechanism checks on

Select the correct option with respect to the following statements:
$(a)$ Angiotensin $II$ constricts arterioles in the kidney to reduce blood flow and decreases blood pressure when blood flow to the afferent arteriole decreases.
$(b)$ Angiotensin $II$ stimulates the adrenal cortex to release aldosterone for more absorption of $Na^+$ and $Cl^-$ ions in the $DCT$.
$(c)$ Blood osmolarity varies with the secretion of aldosterone and $ANP$.

Urinary excretion of $Na^+$ is regulated by

Resorption of water and electrolytes by distal tubules of the kidney,thereby reducing the loss of water through urine (diuresis),is performed by:
