Question: 136
1. Which of the following would most likely be filtered through the glomerulus into Bowman's space?
- A. Erythrocytes
- B. Monosaccharides
- C. Platelets
- D. Proteins
Correct Answer: B
Explanation:
The glomerulus functions like a sieve; small molecules dissolved in the fluid will pass through the glomerulus, including glucose, which is later reabsorbed. Large molecules, such as proteins, and cells, such as erythrocytes and platelets, will not be able to pass through the glomerular filter.
