Nephron Structure and Functions · NCERT Biology

Which part of the nephron is lined by simple cuboidal brush border epithelium to increase the surface area for reabsorption?

  1. Bowman's capsule (parietal layer)
  2. Proximal Convoluted Tubule (PCT)
  3. Ascending limb of Henle's loop
  4. Distal Convoluted Tubule (DCT)
Show answer and explanation

Correct answer: Proximal Convoluted Tubule (PCT)

The PCT is specialized for maximum reabsorption. Its brush border epithelium significantly increases the surface area, allowing nearly 70-80 percent of electrolytes and water to be reabsorbed.
