A Proximal tubule may be defined as the portion of the nephron that lies in between Bowman's capsule and the loop of Henle.

The major function of the proximal tubule is to reabsorption of sugar, sodium, chloride ions, and water from the glomerular filtrate. It decreases the volume of tubular fluid.
