NEPHRONS - The Kidneys' Filtration Units. Nephrons are microscopic tube-like structures in the kidneys that filter the blood and cause wastes to be removed. They are the most basic structures of the kidney's anatomy, and are an integral part of the urinary system. Each kidney contains over one million of them.
Filtration is the process of separating suspended solid matter from a liquid, by causing the latter to pass through the pores of some substance, called a filter. The liquid which has passed through the filter is called the filtrate.The filter may be paper, cloth, cotton-wool, asbestos, slag-or glass-wool, unglazed earthenware, sand, or other porous material. Filtration is very frequently employed in chemical technology, and it often presents great difficulties.r the filtrate may be drawn upwards through the filter, which is suspended in the liquid to be filtered; thus clogging does not occur so easily, as a large part of the precipitate settles to the bottom of the vessel and does not come in contact with the filter until most of the liquid has been drawn off.
