Question

Sodium reabsorption in the distal convoluted tubule is accelerated by the secretion of which mineralocorticoid?

Answer 1

Aldosterone is the mineralocorticoid that accelerates sodium reabsorption in the distal convoluted tubule.

Step-by-step explanation:

Aldosterone is the mineralocorticoid that accelerates sodium reabsorption in the distal convoluted tubule.

Here's a step-by-step explanation:

1. Aldosterone is a hormone synthesized by the adrenal cortex that affects osmotic balance.
2. It regulates sodium levels in the blood by enhancing the reabsorption of sodium ions in the kidney tubules.
3. In the distal convoluted tubules, aldosterone stimulates the synthesis and activation of the sodium-potassium pump.
4. As a result, sodium passes from the filtrate into and through the cells of the tubules and ducts, into the extracellular fluid, and then into the capillaries.
5. Water follows the sodium due to osmosis.
6. This process increases blood sodium levels and blood volume.
