glomerulus and glomerular (bowmans capsule)
what does renin do
coverts angiotensinogen to angiotensin 1
what is angiotensin II and what is its role
hormone released by posterior pituitary
acts to increase water reabsorption through aquaporin channels in DCT and CD
decreases GFR
increase BV BP

increase BP,BV
increase Na reasorption, H2O
decrease K+
in DCT
