Effect of antidiuretic hormone (ADH) on the kidney:
Antidiuretic hormone (ADH), also known as vasopressin, is a hormone produced by the hypothalamus and released by the posterior pituitary gland. Its main function is to regulate the body's water balance by controlling the amount of water reabsorbed by the kidneys. ADH acts on the distal convoluted tubules and collecting ducts of the nephron in the kidney.
The effect of ADH on the kidney is to:
1. Increase the permeability of the distal convoluted tubule of nephron to water:
- ADH increases the permeability of the distal convoluted tubule and collecting ducts to water by inserting aquaporin-2 channels into the cell membrane.
- This allows water to be reabsorbed from the filtrate back into the bloodstream, reducing the amount of water excreted in the urine.
2. Decrease the excretion of water:
- By increasing water reabsorption, ADH reduces the amount of water excreted in the urine.
- This helps to concentrate the urine and conserve water in the body.
3. Conserve body fluids:
- ADH helps to maintain adequate fluid levels in the body by reducing water loss through urine.
- This is especially important in situations where the body needs to conserve water, such as during dehydration or low water intake.
4. Regulate blood osmolality:
- ADH plays a crucial role in regulating blood osmolality by controlling the concentration of solutes in the blood.
- When blood osmolality is high, ADH is released to increase water reabsorption and decrease urine output, helping to dilute the blood.
In conclusion, the main effect of antidiuretic hormone (ADH) on the kidney is to increase the permeability of the distal convoluted tubule and collecting ducts of the nephron to water, leading to increased water reabsorption and decreased urine output. ADH helps regulate the body's water balance and conserve fluids in situations where water conservation is necessary.

Effect of antidiuretic hormone (ADH) on the kidney:
Antidiuretic hormone (ADH), also known as vasopressin, plays a crucial role in regulating the body's water balance by affecting the kidneys. Here is how ADH affects the kidneys:
Increases the permeability of the distal convoluted tubule of nephron to water:
- ADH acts on the collecting ducts and the distal convoluted tubules of the nephron in the kidney.
- It increases the permeability of these tubules to water by inserting water channels called aquaporins into the walls of the tubules.
- This allows for the reabsorption of water from the filtrate back into the bloodstream, leading to a concentrated urine and preventing excessive water loss from the body.
In conclusion, the main effect of antidiuretic hormone (ADH) on the kidney is to increase the permeability of the distal convoluted tubule of the nephron to water, facilitating water reabsorption and maintaining proper water balance in the body.
