Document Summary
Injects the virus" dna or rna into the host cell. Lymphocytes: white blood cells responsible for immune response (t and b cells) Macrophage (category of white blood cells: phagocyte)-known as big eater and will scavenge and consume dead cells/waste products/foreign invaders. Antigen: foreign substance that triggers the immune response by letting system know it has been invaded. Antibodies: proteins that match specific antigens and mark them for destruction. Incubation period: contagious but have no symptoms: organism is reproducing. Autoimmune disease: immune system attacks own body. Opportunistic diseases: they take the opportunity to infect you while your immune system is compromised (often used with aids) Phagocytes- (cid:498)cell eating(cid:499: macrophage (cid:498)big eater(cid:499) Lymphocytes: b cells: produce antibodies (key players in humoral response in blood, helper t cells (cell mediated, killer t cells, suppressor t cells, memory t and b cells. Macrophages display the antigen on their surface. Antibodies attach to antigens, marking them for destruction.
