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