Explain what ADH is and its effect on the body (8)

Antidiuretic hormone is a peptide hormone that is produced in the hypothalamus and it regulated the blood solute levels in the collecting ducts of the kidney hypothalamus detects solute concentration and if blood is too concentrates the pituitary gland releases ADH ADH stimulates the water channels which increases permeability Water moves through the aquaporins by osmosis into the blood which makes the urine more concentrated if blood is hypotonic no ADH is released = water isn't reabsorbed from collecting duct = urine is more dilute
