Please give me the answer to the A-level Biology Question Explain how anti-diuretic hormone (ADH) is released and acts on cells in the collecting duct wall?
A-level Biology Help >>>>> Define how anti-diuretic hormon (ADH) can be released, and is able to affect cells within the wall of the collecting duct? Hypothalamus-specific osmoreceptors are able to detect changes in the blood's water-potential which stimulates neurosecretory cell to release and produce ADH. ADH moves through the axon and to the terminal bulb located in the anterior pituitary gland . It is then released into the capillaries as well as the blood stream , where it acts on the wall of the collecting duct of Nephrons.
ADH is identified by the cell surface receptors located on the wall of the collecting conduit which causes vesicles with water permeable channels (water permeable channels) to form and to be introduced into the cell's surface membrane. This permits the absorption of water into the bloodstream.
