- - - - Hydrogen
  - - - The enzyme Renin
        released by the kidney
        into the blood
        
        Renin converts
        angiotensinogen to
        angiotensin I (in Liver)
        
        Angiotensin I
        converted to
        angiotensin II by ACE
        
        Angiotensin II causes
        release of Aldosterone
        from the adrenal cortex
        
        Aldosterone increases
        renal sodium &
        water absorption
        
        Increased
        blood pressure
        
        Angiotensin II triggers
        vasodilation & releases ADH
      - Increases blood pressure
    - - Inhibits reabsorption of Na & water
      - Atrial stretch
  - - - Erythropoeisis (hypoxia)
    - - Increases bone formation

    - - Renal corpuscle
        
        Glumerulus
        
        Bowman's capsule
      - Renal tubules
        
        • Proximal convoluted tubule
        • Loop of Henle
        • Distal convoluted tubule
    - - Renal cortex

        • Electrolytes
        • Amino acids
        • Glucose
    - - Abuminuria
        
        Oedema
    - - • Diameter of efferent
        • Leaky capillaries
