Innate Immunity Flashcards
Skin and mucous membranes (epithelial cells)
Mechanical defenses; e.g. washing hands, sweating
Chemical defenses; e.g. low pH,
Mucosal-associated lymphoid tissue (MALT)
Mechanical and chemical defenses
SALT: skin associated lymphoid tissue
Mechanical and chemical defenses
GALT: gut associated lymphoid tissue
Mechanical and chemical defenses
BALT: bronchial associated lymphoid tissue
Mechanical and chemical defenses
Diffuse tissues of the urogenital systems
Mechanical and chemical defenses
Phagocytic cells
Phagocytosis: ingest and kill bacteria and fungi
• neutrophils
Ingest and kill bacteria
• macrophages
Ingest and kill foreign cells
Proinflammatory cells
Induce host defenses and inflammation
macrophages
Strategic participants in certain specific immune
reactions
• mast cells
Trigger local inflammatory reactions and responsible for
many allergic symptoms
• eosinophils
Active in worm and fungal infections, allergy, and
inflammatory reactions
• basophils
Function in inflammatory events and allergies
platelets
Involved in blood clotting and inflammation
