Innate immunity is the body's first line of defense against infections, providing a rapid, non-specific response to pathogens. It relies on physical barriers like the skin and mucous membranes, as well as immune cells such as macrophages, neutrophils, and dendritic cells that recognize and respond to common microbial features. Innate immunity also involves soluble molecules like cytokines, complement proteins, and antimicrobial peptides that help eliminate invaders and activate the adaptive immune system. This system is crucial for immediate protection and maintaining immune homeostasis.
