Which process reduces the concentration of urea in the blood of humans?

Answer 1

All the blood is filtered by the kidneys, many times a day. Almost everything in the blood (except for the cells and large proteins) moves from the blood to the Bowman's capsule in the glomerulus of the nephron (the functional unit of the kidney). This includes urea. As the filtrate moves along the nephron, it changes, becoming less like blood and more like urine, until it finally exits through the ureter.
Our bodies form urea because it is our way of getting rid of nitrogenous wastes. When we eat protein, we break it down into its constituent animo acids. When the amino acids in turn are broken down, we are left with nitrogen, which left on its own would form ammonia with hydrogen. Since ammonia is toxic, our bodies expend energy to form urea, which is less toxic, and is filtered out in the kidneys, as described above.
