  • The Kidneys
    • Ultraflitration
      • 2) High pressure squeezes water, urea, salts + glucose into Bowman's capsule (through membrane)
      • 3) Filtered liquid = glomerular filtrate
    • Reabsorption
      • 1) All glucose reabsorbed
        • Proximal convulated tube
        • Active transport
      • 2) Sufficient salt reabsorbed
      • 3) Sufficient water reabosorbed
        • Collecting duct
    • Release of wastes
      • Remaining substances form urine
        • Water, salt + urea
        • Continues out of nephron + into bladder
        • Released via urethra
    • Osmoregulation
      • Antidiuretic hormone (ADH) controls water content
        • Makes nephron wall more permeable
        • Made in pituitary gland
        • Brain monitors water content of blood
          • If water content too high or low, negative feedback mechanism triggers back to normal
