Structure of the Nephron :
Each Nephron has basically two parts:
1. Malpighian body
2. Renal tubule
1. Malpighian Body:
1. It consists of Bowman’s capsule and bunch of fine blood capillaries called the glomerulus.
2. Glomerulus develops from afferent arteriole. It gives rise to an efferent arteriole.
2. Renal Tubule :
1. It has three parts.
i). Proximal Convoluted Tubule (PCT),
ii). Loop of Henle
iii). ‘U’ shaped second or Distal Convoluted Tubule (DCT)
2. Distal convoluted tubule open into a COLLECTING TUBE. Collecting tubes form PYRAMIDS and CALYCES which open into PELVIS.
3. Pelvis leads into the URETER.
4. All the parts of the renal tubule are covered by a network of PERITUBULAR CAPILLARIES fromed from EFFERENT ARTERIOLE
5. The peritubular capillaries join to form RENAL VENULE, which joins the other venules to form RENAL VEIN.
