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

Options

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

Answer

C

Explanation

From the Bowman's capsule the glomerular filtrate enters the proximal convoluted tubule (PCT). PCT is surrounded by a network of pertiubular capillaries and is the seat of reabsorption. About 75% of glomerular filtrate is normally reabsorbed in PCT before reaching the loop of Henle.
The reabsorbed meterials include glucose, amino acids, vitamins, hormones, sodium, potassium, chlorides, phosphates, bicarbonates, most of the water and some urea, etc.
