Controlling Blood water potential

• Controlling Blood Water Potential

  The Kidneys Regulate the Water Potential in the Blood
• Controlling Blood Water Potential

  Absorption is Controlled by Hormones
• Blood water potential mainly in plasma
• The Loop of Henle Maintains a Sodium Ion Gradient

  1. The Loop of Henle of the kidneys is made of a descending and ascending limb

  2. The descending limb is permeable to water

  3. The ascending limb is impermeable to water
• ADH Level Rises


  We Save Water
• ADH Level Falls


  When we are Hydrated
• As ADH levels fall, a large amount of urine is produced and we are dehydrated
• If you don't understand what ADH does, you'll be in urine trouble
• The water content of the blood is regulated by absorption in the proximal convoluted tubule and collecting duct
