ADH and Collecting Duct

• Effect of ADH on collecting duct of the nephron

  If water potential of the blood is too high, less ADH is released leading to less permeability to water in the collecting duct. If water potential is too low, more ADH is released leading to more permeability to water in the collecting duct
• ADH (antidiuretic hormone) is produced by and released from the pituitary gland in the brain
• ADH release and its effect on the collecting duct

  If water potential of the blood is too low, more ADH is released from the pituitary gland and the collecting duct becomes more permeable to water. This leads to less water remaining in the tubule, and more entering blood vessels surrounding the tubule. Less water is released in urination
• ADH

  Antidiuretic hormone which 'prevents you urinating'
