Maximum reabsorption takes place in which part of the nephron?
Correct answer: D. Proximal Tubule
- A. Distal Tubule
- B. Villi
- C. Cortical Tissue
- D. Proximal Tubule
Explanation
[A] Most of the reabsorption does not occur in DCT cells[B] Villi increases the surface area for absorption in Intestine not in nephron[C] Cortical tissue does not exists in nephron[D] most of the selective reabsorption occurs in the PCT cells, reabsorption of glucose occurs completely and 60 to 70% of selective reabsorption occurs in PCT cells but some also occurs n DCT cells e.g of water

About Kidney and Urinary System
The kidney and urinary system remove nitrogenous wastes, regulate water and ion balance, and help maintain blood pH through filtration, selective reabsorption and secretion. Questions cover nephron structure, ultrafiltration, the loop of Henle, collecting ducts, urine formation and the roles of ADH and aldosterone, while distinguishing excretion from egestion.
