What is the Innate Immune System? – Video

Video at a Glance

• The innate immune system is broken down into chemical immunity, containing complement and coagulant proteins, and innate immune system cells.
• The myeloid progenitor line is responsible for innate immune protection.
• Mast cells and basophils are histamines, while neutrophils, eosinophils, and tissue macrophages are phagocytic. All of these are responsible for innate immunity.
• When a cell phagocytizes, its liposomes break down bacteria, secrete chemokines to start inflammation, and present antigens to the adaptive arm of the immune system.
• The chemical secreting cells include three protein classes: albumin, complement/clotting, and immunoglobulins.
• As a group, complement proteins cause opsonization, activate degranulation of mast cells, possess chemotaxis factors, and initiate membrane attack complexes.
