Nephrons : Renal Corpuscle and Filtration Membrane, Arterioles and Vasa Recta -

  • Each kidney has nearly one million complex tubular structures called nephrons which are the functional units.
  • Each nephron is supplied with a tuft of high-pressure capillaries fed by the afferent arteriole, called the glomerulus.
  • The rest of the nephron consists of a continuous sophisticated tubule whose proximal end surrounds the glomerulus and is called the Bowman’s capsule.
  • The glomerulus and Bowman’s capsule together form the renal corpuscle or Malpighian Body.
  • After passing through the renal corpuscle, the capillaries form a second arteriole, the efferent arteriole.
  • These will next form a capillary network around the more distal portions of the nephron tubule, the peritubular capillaries and vasa recta, before returning to the venous system.
  • The outermost layer of the Bowman’s capsule is called the parietal layer and is made up of simple squamous epithelium.
  • The visceral layer is closely associated with the glomerulus. 
  • The visceral layer is made up of unique cells called podocytes. 
  • Podocytes are highly specialized cells of the visceral layer of the glomerular capsule of the renal corpuscle of the nephron of the kidney. 
  • These are called podocytes because they possess foot-like projections called the pedicels. 
  • The space between the pedicels is called slit pores or filtration slits, through which the glomerular filtrate filters.
