AAbout 120 days
BAbout 30 days
CAbout 10 days
DAbout 2 days
Answer & Solution
Correct answer: C. About 10 days
1. Platelets remain in the circulation only about 10 days.
2. They are then phagocytized by macrophages, the same cells that clear worn-out erythrocytes.
3. About 120 days is the erythrocyte lifespan, so that option belongs to the red cell line.
