Which one of the following statements in regard to the excretion by the human kidneys is correct?
Options
- ADescending limb of Loop of Henle is impermeable to water
- BDistal convoluted tubule is incapable of reabsorbing HCO ₃
- CNearly 99 per cent of the glomerular filtrate is reabsorbed by the renal tubules
- DAscending limb of loop of Henle is impermeable to electrolytes
Correct answer
C. Nearly 99 per cent of the glomerular filtrate is reabsorbed by the renal tubules
Step-by-step solution
The plasma fluid that filters out from glomerular capillaries into Bowman's capsule of nephron is called glomerular filtrate. A comparison of the volume of the filtrate formed per day (180 ~L / day) with that of the urine released (1.5 ~L ) , suggests that nearly 99 per cent of the filtrate has to be reabsorbed by the renal tubules. This process is called reabsorption.
