| The largest lymph vessel is the: | Thoracic duct |
| Movement of the lymph takes place by the contraction of ___________ and back flow is prevented by the presence of ________. | muscles; valves |
| Name examples of lymphatic organs: | Thymus, spleen, tonsils, lymph nodes, appendix |
| Which lymph organ may become swolen during infections? | Lymph nodes |
| Barriers to disease, such as intact skin, are examples of____________________ defenses. | Non-specific (innate) |
| The cardinal signs of inflammation are: | Redness, heat, pain, swelling |
| A group of 20 plasma proteins that providesa a nonspecific defense is called: | Complement |
| Activation of complement proteins is called: | Complement fixation |
| B lymphocytes become _____________ which produce ______________ | plasma cells; antibodies |
| The type of lymphocyte that attacks foreign cells is a(n): | T killer cell |
| The type of lymphocyte that activates T cells and B cells is: | Helper T cells |
| Antibodies are made in response to and combine with: | Antigens |
| Which immune response is the greatest, primary or secondary? | Secondary |
| How is an immune response measured? | Antibody titer |
| Why are booster shots given? | To boost antibody tide |
| What general type of immunity does vaccination give? | Artificial active immunity |
| Obtaining antibodies through breast-feeding gives ___________________________. | natural passive immunity |
| Severe allergic reactions may result in: | Anaphylactic shock |
| Rheumatoid arthritis and myasthenia are examples of: | Autoimmune disease |
| The right lymphatic duct is located in the: | Right upper quarter of the body |
| The thoracic duct is located: | Everywhere but the right upper quarter |
| Give a definition for Nonspecific Defenses. | Nonspecific defenses are barriers and are not directed against a particular organism. |
| A pathogen is a: | Disease-causing organism |
| Examples of nonspecific defenses are: | Intact skin, mucous membranes, lysozomes, stomach pH, wandering macrophages, inflammation, and neutrophils |
| Give a definition for and describe the process of opsonization: | Opsonization is to make tasty. Complement proteins recognise disgused pathogens, stick all over them, ans signal macrophages that there is something wrong with the cells. |
