Removal of proximal convoluted tubule from the nephron will result in:
Correct answer: C. More diluted urine
- A. No change in quality and quantity of urine
- B. No urine formation
- C. More diluted urine
- D. More concentrated urine
Explanation
The proximal convoluted tubule is involved in the active and passive absorption of solutes like sodium, potassium, bicarbonate, glucose, amino acids etc. present in the filtrate and passing it to the capillaries.Due to the solute absorption, water potential is lowered in the capillaries and so, the water from the filtrate also moves across the proximal convoluted tubule into the capillaries.Therefore, the removal of PCT will result in the formation of highly dilute urine.Hence, the correct answer is More diluted urine.

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.
