The Bowman’s capsule along with the glomerulus is known as Malpighian corpuscle or Renal corpuscle. Bowman’s capsule is a double-walled cup-like structure. The wall is made of epithelial tissue. The hollow of the cup is occupied by the glomerulus. Blood flowing through the glomerulus is filtered, which is the first step in urine formation and is called ultrafiltration.
The filtration membrane is made up of
- The endothelium of glomerular capillaries.
- The epithelium of Bowman’s capsule
- The basement membrane between the two.
