Final answer:
Aldosterone receptors are found in the distal convoluted tubule and collecting ducts of the kidneys. Aldosterone stimulates sodium reabsorption and water retention, leading to an increase in blood volume and sodium levels.
Step-by-step explanation:
Aldosterone receptors are found in the distal convoluted tubule and collecting ducts of the kidneys. Aldosterone stimulates the synthesis and activation of the sodium-potassium pump in these cells, causing an increase in blood sodium levels and blood volume. It also promotes water retention and reduces urine output.
