In which part of the nephron, does maximum reabsorption of water occurs?

The human excretory system is composed of 1 pair of kidneys. 

The nephron is the structural and functional unit of the kidney. 

The body of the nephron is divided into renal corpuscle, PCT, Henle's loop and DCT. 

The PCT is lined by cuboidal epithelium with a brush border. 

The brush border increases the surface area for the absorption of water and other substances. 

Hence in the nephron, water absorption is maximum (90%) in the Proximal convoluted tubule.
