2.78B describe the role of ADH in regulating the water content of the blood

ADH (Anti-Duretic Hormone): produced by the pituitary gland and affects the permeability of collecting duct to re-absorb water back into blood to regulate water levels in the body.

Low Levels
High Levels
-hypothalamus detects low levels of water 
-Hypothalamus detects high levels of water
-Hypothalamus stimulates pituitary gland to produce more ADH
-Hypothalamus stimulates pituitary gland to produce less ADH
-More ADH: more permeable collecting duct
-Less ADH: less permeable collecting duct
