How is the release of ADH triggered? (5)

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
