hi I am antidiuretic hormone I am made by hypothalamus in the brain and stored in the posterior pituitary gland
you won't dare
mommy I am scared
I am the person that makes your kidneys absorb more water from the forming urine
I travel in the bloodstream to the kidneys. Once at the kidneys, I change the kidneys to become more permeable to water by temporarily inserting water channels, aquaporins, into the kidney tubules. the Water moves out of the kidney tubules through the aquaporins, reducing urine volume.
how do you even work?
When water levels in the blood are optimal, they are considered to be in a state of homeostasis. When homeostasis exists, the hypothalamus tells the pituitary gland to release the normal amount of ADH, telling the kidneys to retain and excrete the right amount of water necessary to retain balance.
