What increases the reabsorption of Na+ when stimulated by aldosterone?

Answer 1

The permeability of proximal tubule of the kidney towards sodium ions increase .

If a drop in blood pressure is noticed, these stretch receptors stimulate the adrenal gland to release aldosterone, which raises the extracellular fluid's osmolarity and increases the body's reabsorption of sodium from sweat, the gut, and urine. Eventually, this causes blood pressure to return to normal.

Aldosterone stimulates the reabsorption of Na+ in the distal tubules and collecting ducts of the kidneys by increasing the synthesis and activation of epithelial sodium channels (ENaC) and sodium-potassium pumps (Na+/K+ pumps).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
