Na⁺ Reabsorption by the Thick Ascending Limb of Henle's Loop

Question

Na⁺ reabsorption by the thick ascending limb of Henle's loop is: A)Inhibited by a decrease in peritubular capillary hydrostatic pressure. B)Inhibited by angiotensin II. C)Increased with increased delivered load of Na⁺. D)Inhibited by potassium-sparing diuretics. E)Increased by natriuretic peptides.

Accepted Answer

Reabsorption of Na⁺ by the thick ascending limb of Henle's loop is increased with an increase in the delivered load of Na⁺. This is because the thick ascending limb is capable of reabsorbing a large amount of Na⁺ via active transport mechanisms. The reabsorption is also dependent on the luminal concentration of Na⁺. As the load of Na⁺ increases, more Na⁺ is delivered to the thick ascending limb, leading to an increase in its reabsorption.

Na+ reabsorption by the thick ascending limb of Henle's loop is:
