That protection starts with innate immunity, your fast, inborn defense system. In this video we break innate immunity into four clear parts so you can remember how the body responds in minutes to hours: Anatomical barriers — mechanical (skin, cilia), chemical (lysozyme in tears, stomach acid), and biological (normal microbiota). Blood proteins — complement and other proteins that tag, attract, and damage invaders. Inflammatory response — histamine, cytokines, vasodilation, and the classic signs: redness, heat, swelling, pain. Cellular response — neutrophils, macrophages, dendritic cells, phagocytosis and antigen presentation. Whether you're reviewing for a biology exam, brushing up on immune system basics, or learning this topic for the first time, this video gives you a clear and reliable guide to how innate immunity keeps you protected. #innateimmunity #biology #immunesystem
