In the hypothalamus and the secreted into the pituitary gland
2 of 7
What does ADH do?
Increase the permeability of the distal convoluted tubule but mainly the collecting duct walls
3 of 7
How does ADH make the walls more permeable?
It binds to receptors which then activated cyclic AMP (a secondary messenger which relays signals received at the surface to other molecules within the cell) causing vesicles containing aquaporins to fuse to the membrane of the collecting duct
4 of 7
What triggers the release of ADH?
Osmoreceptors in the hypothalamus detect the low water potential of blood, they send nerves to the posterior pituitary which releases ADH
5 of 7
What type of a system is osmoregulation?
Negative feedback system
6 of 7
What other thing does the kidneys control in terms of homeostasis?
Blood pressure- Baroreceptors in hypothalamus detect high blood pressure, causes more ADH to be released, blood volume reduced due to less water & blood pressure reduces
