Aldosterone is a hormone produced by the adrenal glands that plays a key role in regulating the balance of water and electrolytes in the body. It acts on the kidneys to increase the reabsorption of sodium and water, while promoting the excretion of potassium. This helps to maintain blood pressure, blood volume, and electrolyte balance in the body.
Antidiuretic hormone (ADH), also known as vasopressin, is a hormone produced by the hypothalamus and released by the pituitary gland. Its main function is to regulate the amount of water excreted by the kidneys. ADH acts on the kidneys to increase the reabsorption of water, leading to a decrease in urine production and an increase in blood volume and blood pressure. This helps to maintain the body's water balance and prevent dehydration.

Aldosterone
- Function: Regulates the balance of sodium and potassium in the body by increasing sodium reabsorption and potassium secretion in the kidneys.
- Source: Adrenal glands
- Target Organs: Kidneys
Antidiuretic Hormone (ADH)
- Function: Regulates water reabsorption in the kidneys, preventing dehydration.
- Source: Hypothalamus (produced) and posterior pituitary gland (released)
- Target Organs: Kidneys
Specific Functions:
Aldosterone:
- Stimulates the reabsorption of sodium ions (Na+) from the distal convoluted tubules and collecting ducts of the kidneys.
- Increases the secretion of potassium ions (K+) into the collecting ducts.
- Maintains normal blood volume and blood pressure by regulating sodium levels.
Antidiuretic Hormone (ADH):
- Increases the permeability of collecting ducts to water, allowing water to be reabsorbed from the filtrate into the blood.
- Reduces urine output and prevents dehydration.
- Maintains the body's water balance and blood osmolality (concentration).
Interrelationship:
- Aldosterone and ADH often work together to maintain fluid and electrolyte balance in the body.
- Aldosterone increases sodium reabsorption, which leads to increased water reabsorption by ADH.
- Conversely, decreased aldosterone levels can lead to increased water loss.
- Function: Regulates the balance of sodium and potassium in the body by increasing sodium reabsorption and potassium secretion in the kidneys.
