Question

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

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

Answer 1

The correct option is C Proximal convoluted tubule

From the Bowman’s capsule, the glomerular filtrate enters the Proximal Convoluted Tubule (PCT). PCT surrounded by a network of peritubular capillaries and is a seat of reabsorption. About 75% of the glomerular filtrate is normally reabsorbed in the PCT before reaching the loop of Henle. The reabsorbed minerals include glucose, amino acids, vitamins, hormones, sodium, potassium, chlorides, phosphates, bicarbonates, most of water and some urea.
