उत्तर
Diagrams A, B, and C represent three types of white blood cells (WBCs) with distinct functions:
- A - Neutrophils: They are responsible for destroying pathogens by the process of phagocytosis.
- B - Eosinophils: They destroy the antigen-antibody complex by phagocytosis. Their number increases in allergic conditions, and they show antihistaminic properties. They are also responsible for detoxification as they produce antitoxins.
- C - Monocytes: Monocytes are actively motile and give rise to macrophages. They are mainly phagocytic and destroy the bacteria and dead or damaged tissue by phagocytosis.
