| The inflammatory response includes all of the symptoms except | vessel constriction |
| The secretion of antibodies by lymphocyte B cells provides | humoral immunity |
| The immunoglobulin found in a mother's milk is | IgA |
| Erythroblastosis fetalis can result if | The Rh- mother is sensitized to the Rh+ antigen and the baby is Rh+ |
| AIDS is such a deadly disease because the AIDS virus attacks and destroys | CD4+ T cells |
| Which of the following are autoimmune diseases | Hashimoto's thyroids and systemic lupus erythemotusus |
| The proteins secreted by plasma cells are called | antibodies |
| A person with anti-A and anti-B antibodies in their blood has what blood type? | type O |
| Precursors of macrophages are called | monocytes |
| The immune response is terminated or decreased by | suppressor T cells |
| Which type of T cell lyses cells that have been infected with viruses? | cytotoxic T cells |
| When a B cell encounters antigen to which it is targeted, it divides rapidly and produces | plasma cells |
| All of the following cells are phagocytic except for | lymphocytes |
| Your body has millions of different antibodies for detecting millions of different antigens because | antibody genes undergo somatic rearrangement and somatic mutation |
| Helper T cells and inducer T cells are also called _______________ cells because of the coreceptor they both have. | CD4+ T |
| Which type of surface marker is present on every nucleated cell in your body? | MHC-I |
| MHC proteins are also called | HLA |
| Activated helper T cells release regulatory molecules called | lymphokines |
| Memory cells | provide an accelerated immune response upon second exposure to a particular antigen |
| What holds together the four polypeptide chains of an antibody? | light chains |
| Of the five classes of antibody heavy chains, which one's function is still partially unclear? | IgD |
| Diseases in which a person's immune system attacks the person's own normal tissue are called | autoimmune diseases |
| The cells that you see when you look at your skin were produced in the | stratum basale |
| Cytotoxic T cells are called into action by the: | decrease in the number of antibodies |
| Complement and antibody are similar in that both: | may make bacteria more attractive to phagocytes. |
| The AIDS virus: | may become dormant in cells. |
| Which cell is correctly matched with its secretion or function? | mast cells - histamine |
| All of the following are part of our antigen specific defense mechanisms except: | acute inflammation |
| Echinoderms have immune systems similar to bony fish in that they possess T and B lymphocytes | False |
| Immunoglobulins have two light chains and two heavy chains. | True |
| IgE is an interleukin involved in allergies. | False |
| T cytotoxic cells produce cytokinins which cause the lysis of other target cells. | False |
| Hemolytic disease of the newborn typically results from immunization of an RH- mother with Rh+ blood from her first pregnancy, the antibodies reacting against the fetus in a later pregnancy. | True |
