How do kidneys clean the body?

Answer 1

A short, simple answer is that urine is a by product of bodily waste. Kidneys filter impurities. If the kidneys do not do their job in filtering, there is build up in the renal tubules (an area of the renal system leading to the kidneys) and also in the bloodstream. This causes trouble in the body systemically and, if left untreated, can lead to numerous medical problems. In short, the kidneys are the body's filters. Urine is the after product of our body's waste once the kidney's have filtered it. Urine leaves our bodies as a sterile fluid. Angie RN

Answer 2

The Kidneys clean the blood by a process of Ultra filtration and Selective Re absorption. This happens in the active section of the kidney called the nephron there are thousands of these in each Kidney. The blood passes through the nephron where it is initially filtered in the Bowmans capsule then as it progresses along the Nephron to the collecting duct. The valuable substances within the blood are re absorped whereas the urea and other waste products are allowed to flow through to the collecting duct, and eventually are excreted out the body. Water reabsorption is a key role of the kidney, this occurs mainly in the loop of henle but most the way through the nephron.
