Question

Maximum reabsorption of useful substances from glomerular filtrate occurs in:

• A. Collecting duct
• B. Loop of Henle
• C. Proximal convoluted tubule
• D. Distal convoluted tubule

Answer 1

The correct option is C Proximal convoluted tubule

Maximum reabsorption of useful substances from glomerular filtrate occurs in proximal convoluted tubule (PCT). PCT is lined by a simple cuboidal brush border epithelium which increases the surface area for reabsorption. Nearly all of the essential nutrients, and 70-80 percent of electrolytes and water are reabsorbed by this segment.
