Composed of a glomerulus and the Bowman's capsule, the renal corpuscle (or Malpighian corpuscle) is the beginning of the nephron. It is the nephron's initial filtering component. The glomerulus is a capillary tuft that receives its blood supply from an afferent arteriole of the renal circulation.The glomerular blood pressure provides the driving force for water and solutes to be filtered out of the blood and into the space made by Bowman's capsule.he glomerulus is a capillary tuft that receives its blood supply from an afferent arteriole of the renal circulation.
