notsponge [240]

Water and sodium ions are reabsorbed in the proximal tubule in a relationship that results in a decrease in tubular fluid volume that is isotonic to plasma.

<h3>What do you mean by Proximal tubule?</h3>

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.

Therefore, water and sodium ions are reabsorbed in the proximal tubule in a relationship that results in a decrease in tubular fluid volume that is isotonic to plasma.
