7.4-7.5

7.4 Specific Defenses (pp.130-131) Define and describe special B cells called plasma cells 7.5 Acquired Immunity (pp.136-137) Define and describe
 * specific defense**- when nonspecific defences fail to prevent an infection, species defence overcomes the infection by getting rid of disease causing agents that have entered the body
 * antigen**- molecules in the immune system reckognizes as feorign to the body
 * antibody**- is the protein produced in responce to the presence of an antigen, and each antibody contains a specific antigen
 * antibody mediated immunity**- specific mechanism of defense in which the plasma cells derived from B cells produce antibodies that combine with the antigens
 * active immunity**-resistance to disease due to the immune system's responce to a microorganism or a vaccine
 * passive immunity**- protection against infectionacquired by the transfer of antibodies to a susceptible person
 * vaccine**-antigens prepared in such a way that they can promote active immunity without causing any disease what so ever
 * antibody titer**-amount of antibodies that are around in a sample of blood serum
 * How was the hepatitis B vaccine prepared?** (p.136)-the same way that you would prepain an antibody titer NO
 * How could a vaccine be a contraceptive** (form of birth control)? (p.332)- It could be this way if it couldn't fight off any other diesases. NO PREGNANCY IS NOT ABOUT A DISEASE, BUT ABOUT SOMETHING FOREIGN


 * How could a vaccine help fight cancer?** (p.416)- It could stop all of the bad cells from dividing in your body RECOGNIZE CANCER CELLS AS DIFFERENT (FOREIGN)
 * Is an AIDS vaccine possible?** (p.351)- NO! Not at all, because it has to do with a blood problem and the only way to fix it would be to get new blood in your body YES A VACCINE IS POSSIBLE
 * Describe "setback"** number 2.-setback is something that is unexpected during a process like surgury, and you typically have to work around it and roll with it NO
 * Describe setback** number 3.-setback is something that is unexpected during a process like surgury, and you typically have to work around it and roll with it NO
