Lets find out about Pitressin or ADH.Antidiuretic hormone or vasopressin helps to manage fluid volume.ADH is secreted by the posterior portion of the pituitary body.The pituitary is split into anterior and posterior portions.ADH is secreted in response to a rise in blood solute concentration.

   

Blood solute concentration is sensed by osmoreceptors within the hypothalamus.ADH is additionally secreted in response to a decrease in fluid volume.ADH may be a hormone that travels within the blood to the kidneys.

ADH promotes fluid retention by the kidneys. ADH has an impact on the distal convolutedtubule and collecting duct of the nephron. Lets take a better look.ADH makes the distal convoluted tubule more permeable to water.ADH promotes the looks of water channels called aquaporins.

Water moves out of the distal convoluted tubule and collecting duct toward the upper soluteconcentration within the interstitium. Water moves into the blood increasing bloodvolume and decreasing blood solute concentration this works to revive homeostasis. We hope you have got learned something about ADHand see you next time.
