Document Summary

Kidneys are used for waste removal as well as salt and water regulation. 300 m/os is the concentration of the blood in the kidneys: maintain ion balance. Na, k, cl, ca: maintenance of body ph. Located behind the abdomen: somewhere near the 11th and 12th ribs. The positing of the kidney is called retroperitoneal. Blood supply enters and exits on the concave side of the kidney: the structure it exits is called the renal artery, the structure that it is carried it out is called the renal vain. The functional unit of the kidney: about 1 million in each kidney. This is the name given to a group of fenestrated capillaries inside bowman"s space. These are so large that everything in the blood can be filtered. Basal lumen helps to filter and prevents proteins from entering bowman"s capsule. Podocytes serve as a third barrier for filtration.
