Choose the correct statement regarding the human excretory system:
A
The human kidney can produce urine nearly 10 times concentrated than the initial filtrate.
B
Presence of glucose and ketone bodies in urine are indicative of Diabetes Mellitus.
C
Dialysis unit contains a fluid which has the same composition as plasma but lacks nitrogenous wastes.
D
Sweat produced by sweat glands is primarily meant for excretion of urea.
Explanation
The presence of glucose and ketone bodies in urine is a classical clinical indicator of Diabetes Mellitus. The kidney can concentrate urine up to 4 times, not 10 times. Dialysis fluid is designed to have the same composition as plasma but lacks nitrogenous wastes to allow them to diffuse out of the blood. Sweat's primary function is cooling, though it removes small amounts of wastes.
