Question

The part of nephron involved in active reabsorption of sodium is

• A. descending limb of Henle's loop
• B. distal convoluted tubule
• C. proximal convoluted tubule
• D. Bowman's capsule

Answer 1

The correct option is C proximal convoluted tubule

Tubular reabsorption is the process that moves solutes and water out of the filtrate and back into your bloodstream.
Sodium is the major positively charged electrolyte in extracellular body fluid. The amount of sodium in the fluid influences its volume, which in turn determines blood volume and blood pressure.
Proximal convoluted tubule is involved in active reabsorption of sodium. The majority (about 70%) of sodium is reabsorbed here, into the cytosol of the epithelial cells of the nephron.
