Anti-diuretic Hormone is a hormone produced by the pituitary gland to control the volume of urine produced by the kidneys.
About Anti-diuretic Hormone
- The kidneys are the target organs for anti-diuretic hormone.
- When the kidneys receive anti-diuretic hormone any water lost from the blood is reabsorbed into the blood causing the volume of urine to be low and its concentration to be high.
- When there is little anti-diuretic hormone the water taken out of the blood in the kidneys is passed on to the bladder via the ureters causing the volume of urine to be high and the concentration to be low.
