Each nephron has two parts:

(i) Glomerulus: It is a tuft of capillaries in Bowman's capsule.
Renal artery$\to$Afferent arteriole (a fine branch of the renal artery)$\to$Glomerulus$\to$An efferent arteriole.

(ii) Renal tubule: It is divisible into
a. Bowman's capsule: It is a double-walled cup-like structure enclosing the glomerulus.
b. Proximal convoluted tubule (PCT): It is a highly coiled structure.
c. Henle's loop: It is a hairpin shaped structure with its descending and ascending limbs.
d. Distal convoluted tubule (DCT): Ascending limb of Henle's loop leads to another highly coiled tubular structure termed as DCT.
e. Collecting duct: It is a straight tube that is formed by the fusion of DCTs of many nephrons. Many collecting ducts converge and open into the renal pelvis through medullary pyramids in the calyces.
