The urinary system has many functions including the following: regulation of glucose levels, blood volume, blood pressure and pH. Also produces hormones and excretion of waste and foreign substances. The kidneys do a major part of the work in the urinary system. The blood flow of the kidneys starts at the renal arteries. From there the renal artery divides into several segmental arteries. Then the segmental arteries goes into the interlobar arteries and then to the arcualte arteries. These arteries divide and make interlobular arteries. These arteries enter the renal cortex and branch into afferent arterioles.
The kidneys are important and we have are lucky to have two of them. We can live with one if we have to. A kidney transplant is one of the few organs that can be taken from a live donner. This is incredible to be able to help someone else and still live to do it.
