The maximum amount of electrolytes and water (70 - 80 %) from the glomerular filtrate is reabsorbed in which part of the nephron?
Correct answer: C. Proximal convoluted tubule
- A. Ascending limb of loop of Henle
- B. Distal convoluted tubule
- C. Proximal convoluted tubule
- D. Descending limb of loop of Henle
Explanation
During glomerular filtration in kidneys, ultrafiltration of blood occurs i.e: almost all the constituents of plasma except proteins pass onto the Bowman's capsule.Then nearly 99% of the filtrate is reabsorbed by renal tubules.The proximal convoluted tubules show maximum reabsorption and nearly all the essential nutrients and 70-80% of electrolytes and water are reabsorbed by this segment.

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.
