Question

Area responsible for reabsorption of water, glucose, sodium phosphate and bicarbonates is
a) glomerulus
b) proximal convoluted tubules
c) collecting duct
d) descending limb of Henle’s loop

Answer 1

The important substances are reabsorbed from the filtrate in the first half of “Proximal Convoluted Tubules”.

The substances that are reabsorbed include sodium, glucose, phosphates, amino acids, bicarbonates, lactate and citrates. This thus acts as a piggy bank or sodium co-transporters.

It helps to move these substances down the electrical gradient into the epithelial cells. Therefore the correct answer is “B”
