Question

multiple select question
select all that apply
choose all that are functions of macrophages.

□ present antigens
□ phagocytize dead cells
□ destroy foreign antigens
□ produce antibodies

Explanation:

Macrophages are immune cells. They present antigens to activate other immune cells (antigen - presenting function), phagocytize dead cells (part of tissue cleanup and immune surveillance), and destroy foreign antigens (like pathogens) through phagocytosis. However, antibody production is done by B - cells, not macrophages. So the functions of macrophages among the options are presenting antigens, phagocytizing dead cells, and destroying foreign antigens.

Answer:

A. Present antigens, B. Phagocytize dead cells, C. Destroy foreign antigens
