Anti-Diuretic Hormone

Question 5

Where is ADH released from and what is its purpose?

Answer 5

ADH is released by the pituitary gland and it targets the collecting duct in the nephron.
When water levels are high, the pituitary gland releases ADH which produces aquaporins in the collecting ducts that allows water to be reabsorbed.

• When water levers are high ADH is released and it makes the collecting duct impermeable so less what can be reabsorbed and more is released
