Innate immunity are square defenses that humans develop square Non-specific

Innate immunity refers to the body's natural, non-specific defenses that are present from birth. These defenses include physical barriers such as the skin and mucous membranes, as well as immune cells like neutrophils and macrophages that can recognize and attack a wide range of pathogens. Unlike adaptive immunity, innate immunity does not require prior exposure to a pathogen to be activated.
