In nephron, most of the reabsorption takes place in the:
Correct answer: B. Proximal tubule
- A. Distal tubule
- B. Proximal tubule
- C. Ascending limb
- D. Descending limb
Explanation
The proximal convoluted tubule (PCT) is the site where ~65- 80% of filtered water, electrolytes, glucose, and amino acids are reabsorbed back into the bloodstream due to its highly permeable epithelium and extensive surface area.

About Homeostasis
Homeostasis maintains a stable internal environment through the kidney and urinary system, thermoregulation and excretion. The kidney topics include filtration, selective reabsorption, urine formation and water balance, while thermoregulation involves sweating, vasodilation, vasoconstriction and hormonal control; excretion is different from egestion, which removes undigested food.
