Question

under normal circumstances, which of the following substances should be found in urine?
a glucose
b blood
c albumin
d nitrogenous wastes

Explanation:

• Glucose: Normally reabsorbed completely in the renal tubules, so not in urine.
• Blood: Red blood cells are too large to pass through the filtration membrane under normal circumstances.
• Albumin: A large - sized protein that is not filtered through the normal glomerular filtration membrane.
• Nitrogenous wastes (e.g., urea): Filtered through the glomerulus and not reabsorbed completely, so present in urine.

Answer:

D. nitrogenous wastes
