The urinary system does more than you might think. The obvious functions of the urinary system are excretory and urine formation which transports storage urine and release, but it does quite a lot more. Since it is a regulator of how much water is in the blood it can impact blood pressure but it can also stimulate blood cell formation. Vitamin D is made from the interaction of sunlight and your skin but it is activated to perform its hormone function by the kidney cells. Your blood must stay within a very narrow range of pH for critical chemical reactions to occur, and to prevent damage to cells and tissues. The Urinary System is vital in keeping the pH in proper balance. Summarizing the previous we can conclude that the urinary system has 7 functions in total. Lets begin by discussing the big picture view of the urinary system. It is comprised by the kidneys, ureter, bladder, and the urethra. Referring to the anatomical position the right kidney is lower than the left kidney due to the liver being large. In a transverse cut and view from above one can see that the digestive organs are in a separate cavity from the urinary system. The peritoneal cavity houses the digestive organs and it houses serous membrane which secretes a small amount of fluid in the cavity that lubricates organs so that they experience very little friction as they move about inside of the body. The kidneys are in the retroperitoneal cavity, literally that means behind the peritoneal cavity. Unlike the digestive organs the kidneys are not allowed to move much when the body moves. They are held in place by perirenal fat, this fat firmly holds them in place. If someone gets to abnormally thin the kidneys can slip causing the ureter to get pinched.

Alkalosis is when the bloods pH increases to become more alkaline, it results in over excitement of the nervous system leading to convulsions. There are key pH changers that can occur; vomiting can lead to alkalosis, diarrhea can lead to acidosis. Kidney disfunction could happen either way, if the kidneys get messed up then blood pH can be all over the place. The body has a buffer system that mixes of a weak acid and a weak base to resist changes in pH, it is the least efficient but it is quick. It includes buffers such as bicarbonate, phosphate, and a few proteins that help too. The respiratory system place a part too, it is a bit slower but it is more effective than the buffer system. The kidney secretion of hydrogen ions, is the most effective but is the slowest. It lowers the pH of the blood and raises pH of the urine.
