  • Homeostasis - Osmoregulation
    • Receptor in the Brain detects an excess in water
      • Processing centre in the brain coordinates a response
        • The Pituitary Gland releases less ADH so the Kidneys reabsorb less water

                • The Pituitary Gland releases less ADH so the Kidneys reabsorb less water
                  • Large amounts of Dilute Urine
            • Receptor in the Brain detects a lack of water
              • Processing centre in the brain coordinates a response
                • The Pituitary Gland releases more ADH so the Kidneys reabsorb more water.
                  • Small amounts of Concentrated Urine
            • Maintaining A Constant Internal Envrinoment
