ASodium ions, amino acids, vitamins
BBlood cells, platelets, antibodies
CUrea, creatinine and uric acid
DGlucose, water and chloride ions
Answer & Solution
Correct answer: B. Blood cells, platelets, antibodies
1. The glomerulus filters mostly by particle size.
2. Large elements such as blood cells, platelets, antibodies and albumen are too big to cross and stay in the capillary.
3. Ions, amino acids, vitamins and wastes are small, so they enter the filtrate freely.
4. That is why the filtrate composition is very similar to plasma apart from the missing cells and large proteins.
