AThey are destroyed in the glomerulus
BThe tubule reabsorbs them instantly
CThe glomeruli filter mostly by particle size
DThey repel the capsule chemically
Answer & Solution
Correct answer: C. The glomeruli filter mostly by particle size
1. The glomeruli filter the blood based mostly on particle size.
2. Large elements like blood cells, platelets, antibodies, and albumin are excluded.
3. Nothing destroys them; they simply never leave the capillaries.
