Renin-Angiotensin System
- Functions
- Controls Ion copositin of the blood
(via stimulation of aldosterone
secretion)
- Increases water reabsorption in distal convoluted tubule
- Increases blood volume
- Increases blood volume
- By increased water
reabsorption (distal convuluted
tubule - via aldosterone)
- Causes vasoconstriction in arterioles
- Throughout the day the blood volume
remains within a normal range and doesnt
change from this despite intake of fluids
- Function of kidneys removing excess fluid
- If blood volume begins to
drop this is reversed by an
increased reabsorption of
water by the kidneys
