When blood pressure falls, renin secreted by certain kidney cells and angiotensiogen
secreted in the liver come together and unite, like two matching parts of a logo. After

constricts the blood vessels and ensures the secretion of aldosterone in the kidneys.
This hormone causes the kidneys to reabsorb much more fluid from the urine. This
chain of operations adjusts the blood pressure, raising it to the proper level.
