1. a compliment protein binds to an antibody molecule attached to a bacterial cell wall or directly to the cell wall- the bound complement protein then interacts with other complement proteins – this attracts phatocytes and stimulates phagocytosis…it will also stimulate inflammation

“A First Date” oftentimes can go very badly.

2. mast cells release histamine/heparin – this stimulates localized inflammation; the end result of inflammation is the replacement or repair of damaged tissue; purposes of inflammation are to perform a temporary repair at the injury site and prevent the access of additional pathogens, to slow the spread of pathogens, and to mobilize defenses

3. fever occurs when the body temp is > 37 degrees Celsius; circulating proteins call pyrogens can reset the thermostat in the hypothalamus and cause a rise in body temp; pathogens, bacterial toxins, antibodies that are bound to their antigens, and WBCs may act as pyrogens

4. it is what is genetically determined; it is present at birth and has no relation to previous exposure to the antigen involved; ie people don’t get the same diseases as goldfish

5. active immunity is produced by antibodies that develop in response to antigens (immune response) and passive immunity is produced by transfer of antibodies from another person; they are both forms of acquired immunity

6. antigen: any foreign substance that stimulates an immune response; pathogen: any disease-causing invader
