Now, once we form angiotensin one, it will then travel into lung cells and also into kidney cells, and it will be activated by using the angiotensin converting enzyme into angiotensin II. And then angiotensin II basically goes on to activate the ADH, the vasoppressin released by the posterior pituitary, which causes our kidneys to become more permeable to water and reabsorb more water into our blood vessels. Now, it also causes the release of aldosterone, which basically causes our kidneys also to reabsorb more water by creating a net movement of ions back into the blood. And it also constricts our arterios, which increases our blood pressure. So all these three effects result in an increase in blood volume, increase in blood flow rate, our perfusion rate inside our kidney, and also increases our blood pressure. And when our blood pressure increases, that can basically react in a negative feedback loop to cause our kidneys, the juxtag glomeryla cells, to stop releasing renan and this is basically how we control our blood pressure inside our body.
