Structure and Function of a Nephron:

A nephron consists of a long coiled tubule and the Malpighian corpuscle. Each nephron functions as an independent unit and produces a miniscule quantity of urine. A nephron can  be differentiated into the following regions:

1. Malpighian Corpuscle:

This consists of two parts:

  • a) Bowman's Corpuscle: This is cup shaped structure which is double walled, in the hollow of which is a network of capillaries called Glomerulus.
  • b) Glomerulus: This is a mass of blood capillaries with an incoming and an outgoing arteriole.
  • 2. Renal Tubule:

    This is the remaining part of the nephron, and is continuous with Bowman's Capsule. It is lined with ciliated epithelium and differentiated into the following regions:

  • Proximal Convoluted Tubule (PCT),
  • .... (More Text Available, Login?)
