Question

The maximum amount of electrolytes and water ($70 - 80$ percent) from the glomerular filtrate is reabsorbed in which part of the nephron?

• A. Ascending limb of loop of Henle
• B. Distal convoluted tubule
• C. Proximal convoluted tubule
• D. Descending limb of loop of Henle

Answer 1

Answer: (C)

Proximal convoluted tubule

Answer 2

During glomerular filtration in kidneys, ultrafiltration of blood occurs i.e., almost all the constituents of plasma except proteins pass onto the Bowman's capsule. Then nearly 99% of the filtrate is reabsorbed by renal tubules. Proximal convoluted tubules shows maximum reabsorption and nearly all the essential nutrients and 70-80% of electrolytes and, water are reabsorbed by this segment.
