Lymphatic
| Question | Answer |
|---|---|
| lymph capillaries converge to form _______ which converge to form ____ | lymphatics vessels; lymphatic trunk |
| lymphatic trunk converge to form _____ | 2 collecting ducts |
| right collecting duct is drained from | right arm, right thorax, neck and head |
| right collecting duct drains into | right subclavian vein |
| thoracic collecting is bigger because | it drains the rest of the body |
| thoracic collecting duct drains into | left subclavian vein |
| lymph nodules | collection of lymphocytes and macrophages; prevalent in gastro tract, resp repro, urinary tracts |
| peyer patch | cluster of nodules in the small intstine |
| primary lymphatic organs | red bone marrow and thymus cuz they form and mature T and B lymphocyte |
| secondary lymphatic organs | spleen, tonsils, lymph node |
| most abundat lymph organ | lymph node |
| lymph node function | filters the lymph and activates immune response |
| why is the lymph node considered bottle neck | several afferent enter and 1-3 effernt exits |
| first line of defense against infection | nonspecific skin (external barrier) |
| second line of defense | non spececific, leukocytes, macrophage, fever, antimicrob bacteria |
| third line of defense | immune system; leaves a memory of pathogen |
| interferon | anti mic protein that alert neighboring cells of infection to prevent them from being infected |
| specificity immunity | immunity targeting one pathogen |
| memory | reexposure to same pathogen cuz body to react quickly |
| cell mediated immunity | lymphocytes atack n destroy foreign cells/ infected cells |
| humoral (antibody mediated) immunity | antibodies |
| nat active immunity | poduction of self antibodies/ t cells |
| artific active immunity | production of self antibody as a result of vaccine |
| nat passive immun | temp immunity from acquiring antibodies from another person (fetus n mother) |
| artific passive immun | termp immunity acquired fom serum with antibodies from another person |
| t cells are formed in _______ and mature in into functional t cells in the _______ | red bone marrow, thymus |
| b cells remain in _________ to mature then sent to the other lymph organs | red bone marrow |
| cellular immunity activates ______ | t lymphocyes |
| role of helper t cells | coordinates humoral and cell mediated - |
| viral protein antigens attach to ________ that causes Tc cells to respons | MHC I |
| foreign antigens that attach to ______ causes helper T cells to respond | MHC II |
| Tc cells role | attack and kill cells |
| Humoral immunity | antibodies release to bind to antigens uses B lymphocytes |
| CD4 | helper t cells attracted to MHCII |
| CD8 | cytotoxic t cell attracted to MHCI |
