Solution

Yes, that's correct. Aldosterone, a hormone produced by the adrenal glands, plays a crucial role in the regulation of blood pressure. Here's how it works:

  1. When blood pressure or blood volume is low, the kidneys release an enzyme called renin.
  2. Renin then triggers a series of reactions that lead to the production of a peptide called angiotensin II.
  3. Angiotensin II stimulates the adrenal glands to release aldosterone.
  4. Aldosterone acts on the cells of the kidney's tubules and prompts them to reabsorb sodium from the urine back into the blood.
  5. As sodium is reabsorbed, it creates an osmotic gradient that promotes water reabsorption as well.
  6. This increase in blood volume helps to raise blood pressure.

So, in essence, aldosterone promotes the movement of sodium and water from the kidney filtrate back into the blood, helping to increase blood volume and blood pressure.
