Science definitions for nephron

[ nĕfrŏn ]

The functional unit of the kidney, in which waste products are filtered from the blood and urine is produced. The nephron consists of a system of tubules in close association with a network of blood vessels. As fluid that is filtered through the glomerulus of the nephron enters the tubules, its composition is gradually changed by the absorption and secretion of solutes, and it eventually leaves the nephron as urine.
