Tubular reabsorption of water, nutrients, and sodium begins in the ____.

A) glomerulus
B) proximal tubule
C) distal tubule
D) loop of Henle

Tubular Reabsorption

Water and solutes move from the filtrate inside a kidney tubule into the peritubular capillaries.

Proximal Tubule

A segment of the nephron in the kidney where a major portion of the reabsorption of water, ions, and nutrients from the filtrate back into the bloodstream occurs.

Glomerulus

A network of capillaries located at the beginning of a nephron in the kidney, where blood filtration takes place.
