How do you macrophages protect your body from infection?

Macrophages protect the body from infection by identifying, engulfing, and digesting pathogens such as bacteria and viruses through a process called phagocytosis. They also release signaling molecules called cytokines that help recruit and activate other immune cells to the site of infection. Additionally, macrophages can present antigens from pathogens to T cells, boosting the adaptive immune response and providing long-term immunity. This multifaceted approach makes macrophages crucial players in the immune system's defense against infections.
