The part of nephron involved in active reabsorption of sodium is: Bowman's capsule, Descending limb of Henle's loop, Proximal convoluted tubule, Distal convoluted tubule

Sodium reabsorption occurs through tubular reabsorption in proximal and distal convoluted tubules only. The proximal convoluted tubule is involved in active reabsorption of sodium into the peritubular capillary network and passive flow of water flows. It accounts for 67%
