ADH & Plasma

what detects dehydration (or high Na+ intake) or over hydration (low Na+ intake)

osmoreceptors in hypothalamus

osmoreceptors in hypothalamus stimulate what

posterior pituitary to manage ADH levels

-dehydration = increase

-over hydration = decrease

ADH effects what

the CD in the kidneys

-increases water reabsorption to decreases water reabsorption

decrease in water reabsorbtion

lowers bp which triggers RAA system to increase blood volume

decreasing ADH has what effect

diuretic

increasing ADH

increases blood volume, increases bloop pressure

decreasing water reabsorption and increasing secretion

(low ADH/diuretic effect)

-increase in volume of urine (dilute urine)

-decrease in volume of blood

-decrease in BP

increasing ADH levels

-decreases urine volume (concentrated urine)

-increases blood volume

-increases in bp
