Example Question #6 : Understanding Other Excretory Physiology
Which of the following would be filtered by the kidney and not found in urine?
Possible Answers:
Proteins
Potassium
Urea
Sodium
Water
Correct answer:
Proteins
Explanation:
Proteins would not be found in the urine because these molecules are too large to pass through the glomerulus of the nephron of the kidney. They would be filtered out and remain in the bloodstream. Meanwhile, all of the other compounds would be present in normal urine.
