2. Phagocytic cells--macrophages
i. Phagocytes include macrophages and neutrophils
ii. Phagocytes engulf and destroy pathogensiii. Phagocytosis is enhanced when pathogens
surface is altered by antibodies or complement proteins
iv. Cell killing is enhanced by respiratory burst
Obj. 6
3. Natural killer cells – attack and lyse body cells infected by viruses or that are cancerous.
Obj. 7 Inflammatory response1. Skin & mucous membranes2. Phagocytic cells3. Natural killer cells
4. Inflammatory response– damaged tissues release histamines–Histamines make vessels leaky, releasing
phagocytes & clotting factors–Phagocytes engulf bacteria–Platelets form clots
Obj. 5 Nonspecific Defenses: things your body uses to defend against ANYTHING
5. Antimicrobial substances–Interferon–Complement proteins
Obj. 8 Fever1. Skin & mucous membranes2. Phagocytic cells3. Natural killer cells4. Inflammatory response5. Antimicrobial substances
6. Fever–Macrophages release pyrogens–Hypothalamus elevates temperature–Liver & spleen supply less iron–Bacteria don’t grow well without iron–Metabolism increases speeding repair.
