Answer:
This question lacks options, options are:
A. glomerular filtration.
B. renal clearance.
C. micturition
D. reabsorption
The correct answer is B.
Step-by-step explanation:
The kidneys remove waste and excess water from the blood (such as urine) and help keep chemicals (such as sodium, potassium, and calcium) in the body balanced. Renal clearance is defined as the volume of blood plasma (ml), which due to the effect of renal function, is free of substance X in the unit of time (in minutes). Substance X becomes part of the urine, that is, renal clearance is the amount of blood that is free of a substance as it passes through the kidney in a unit of time.
