Basically, a nephron comprises a renal tubule and blood vessels. The renal tubule expands into a cup-shaped structure called the Bowman's Capsule, which contains a ball of capillaries known as the Glomerulus. The Glomerulus is the primary structure of the filtering process.

Whatâs left in the kidney after filtration of the blood; the toxins, salts, urea, ammonia, excess water, etc becomes urine.
