| Function of lymphatic system | fluid recovery, immunity and lipid absorption |
| where does the interstitial fluid from tissues enters the lymphatic system | lymphatic capillaries |
| from the lymphatic capillaryies the lymph fluid enters into the _______ | lymph nodes where it is filtered |
| lymph nodes then move lymph into | collecting vessels |
| collecting vessels become ______ | lymphatic trunks there are 6 truncts |
| lymphatic trunks empty into _______ | collecting ducts |
| what are the 2 major collecting ducts | right lymphatic duct and the thoracic duct |
| right lymphatic duct drains lymph from | neck and right arm |
| thoracic duct drains lymph from | from left arm, thoracic region, abdomen |
| where do the right lymphatic duct and the thoracic duct empty | subclavian vein back into the circulatory system |
| major organs of the lymphatic system are | thymus, spleen, bone marrow, lymph nodes, tonsils |
| what 2 organs are known as the primary lymphatic organs | thymus and bone marrow |
| what organs are the secondary lymphatic organs | spleen, lymph nodes, and tonsils |
| lymphatic cells | Natural killer cells, T lymphocytes, B lymphocytes, macrophages, dendritic cells and reticular cells |
| Natural killer cells | attack cells and kill them |
| T lymphocytes | specific cellular immunity |
| B lymphocytes | humoral immunity produces antibodies to destroy foreign substances |
| macrophages | help in phgocytosis |
| dendritic cells | located in skin |
| reticular cells | filter lymph and provide immunity |
| what are the two types of lymphatic tissues | diffuse and nodules |
| the cells in diffuse lymphatic tissue are | scattered |
| the cells in nodular lymphatic tissue are | congregated |
| where are the lymphatic cells made | in the bone marrow |
| what are the filtering units of the lymphatic system | lymph nodes |
