Decreased blood pressure

Decreased baroreceptor firing

Signal medulla oblongata

Decreased parasympathetic output

DECREASED BLOOD PRESSURE

Increased Sympathetic output

Decreased sympathetic output

Decreased vasodilation

Increased vasoconstriction

Adrenal gland releases epinephrine/ norepinephrine

Increased heart rate

Increased cardiac output

Decrease in profusion detected by JGA cells

Renin release by JGA cells

Angiotensinogen cleaved into angiotensin I

ACE converts angiotensin I to angiotensin II

Angiotensin II stimulates aldosterone release and increases vasoconstriction

Aldosterone increases water abd

Increased blood volume

Increased ADH release from posterior pituitary

Increased water reabsorption in the kidneys

Increased number of aquaporins in DCT and collecting duct to decerease osmolarity
