Now, what the angiotestin two also does is it basically goes on and stimulates the release of the antidiauretic hormone ADH that is stored inside the posterior pituitary gland and produced by the hypothalamus. So ADH, also known as vasopressin, basically causes our kidneys to reabsorb more water. It becomes more permeable to water the cell membrane. And so water increases inside our blood plasma, and this increases our blood pressure inside our blood vessel. Now, angiotensin two actually also constricts our blood vessels, and that causes an increase inside our blood vessels. So more specifically, it causes the constriction of our arterioles throughout the body as well as inside our kidneys.
