Which immunity is innate?

Innate immunity is the body's first line of defense against pathogens and is present from birth. It includes physical barriers like the skin and mucous membranes, as well as immune cells such as macrophages and neutrophils that respond quickly to infections. This type of immunity is non-specific, meaning it does not target specific pathogens but rather responds to a wide range of threats. Additionally, innate immunity involves various biochemical mechanisms, such as the release of antimicrobial peptides and inflammatory responses.
