Document Summary
Describe homeostasis as it applies to body fluids and osmolarity. The osmolarity of the blood is about 300 mosm/l. The basic function of the kidneys is to remove nonessential substances from the plasma, including wastes metabolites, excess water, and electrolytes: also, the kidneys recover essential substances like glucose. In doing so the kidneys play a major role in regulating the water levels, the chemical concentrations of the fluid compartments, and ph of the blood. Draw a diagram of the kidney and label the major components. Draw a diagram of the kidney blood flow: blood flows to the kidneys through the renal artery. This large artery branches into interlobar arteries that in turn branch into arcuate arteries. The blood in the arcuate arteries flows through the interlobular arteries to supply the nephron. The blood supply to the nephron drains into the interlobular vein, the arcua vein, the interlobar vein and then into the renal vein.
