| allergist | specializes in allergic reactions |
| immunologist | specializes in treating immune system disorders |
| oncologist | specializes in diagnosing malignant disorders; cancer, tumors |
| villi | are small finger-like projections that line the small intestine. blood vessels in the Villi absorbs most of the nutrients from digested food directly into the blood stream |
| lacteals | specialized structures located in the villi and are specialized structure's of the lymphatic system. Fats and fat soluble vitamins that that can't adsorbed by the blood stream, are absorbed by the lacteals |
| lymphatic system | removes waste products and excess fluid created by cells. It destroys pathogens and takes away foreign substances. |
| Structures of Lymphatic System | lymph, lymphatic vessels, ducts, lymph nodes, tonsils, thymus, spleen, lacteals, peyer's patches, vermiform appendix and lymphocytes |
| lymphatic system | is sometimes referred to as the secondary circulatory system |
| Interstitial fluid | is plasma from arterial blood, comes from the capillaries into spaces between the cells. the fluid transports food, oxygen and hormones to the cells |
| Lymphatic Capillaries | are microscopic located near the surface of the body. they separate briefly to allow lymph to enter the capillary and this action of the cells as they close forces the lymph to move forward |
| Lymphatic Vessels | flows from lymphatic capillaries into the lymphatic vessels located deeper with the tissues they have valves to prevent the backward flow |
| right lymphatic duct | collects lymph from the right side of the head and neck, upper right quadrant of the body and arm, it empties into the right subclavian vein. |
| thoracic duct | is the largest lymphatic vessel in the body collects lymph from the left side of the head and neck and upper quadrant of the trunk and left arm and the entire lower portion of the trunk and both legs it empties into the left subclavian vein |
| lymph nodes | unfiltered lymph flows into the nodes and here destroy harmful substance; bacteria, viruses and malignant tumors. additional structures within the node filter the lymph and remove impurities. then the lymph leaves the node and continues |
| Cervical lymph nodes cervic/al | are located along the sides of the neck cervic / means neck al/ means pertaining to |
| Axillary lymph node axill/ary | are located under the arm in the armpit. axill/ means armpit ary / means pertaining to |
| Inguinal lymph nodes inguin/al | are located in the area of the lower abdomen inguin / means groin al / means pertaining to |
| tonsils | are three masses of lymphoid that form a protective ring around the throat. they prevent pathogens from entering the body through the nose and throat |
| adenoids | also known as nasopharyngeal tonsils are located in the nasopharynx |
| palatine tonsils | located on the left and right sides of the throat they are visible through the mouth. palatine means hard and soft palates |
| lingual tonsils | located at the base of the tongue. lingual means tongue |
| thymus | located superior (above) the heart. is an endocrine glad that assists the immune system |
| Peyer's patches | located on the walls of the ileum. ileum is last section of the small intestine. this protects against the entry of pathogens through the digestive system |
| vermiform appendix | hangs from the lower portion of the cecum. cecum is the first section of the large intestine |
| spleen | sac like mass of lymphoid tissues: it filters microorganisms and foreign material from the blood. it forms lymphocytes and monocytes that are specialized white blood cells they play a role in immune system |
| hemolytic hem/o/lytic | the spleen has a hemolytic function of destroying worn-out red blood cells so they can be reused hem/o means blood -lytic / means to destroy |
| lymphadenitis lymphaden/itis | inflammation of the lymph node lymphaden / means lymph node itis / means inflammation |
| lymphadenopathy lymphaden/o/pathy | any disease process affecting a lymph node or nodes lymphaden/o / means lymph node pathy / means disease |
| lymphangioma lyphangi/oma | is a benign tumor formed by an abnormal collection of lymphatic vessels do to congenital malformation of the lymphatic system lymphangi / means lymph vessels -oma / means tumor |
| splenomegaly splen/o/megaly | enlargement of the spleen; caused by an injury, infectious disease; ( mononucleosis), or abnormal functioning of the immune system |
| splenorrhagia splen/o/rrhagia | bleeding from the spleen splen/ means spleen rrhagia / means bleeding |
| lymphoscintigraphy | diagnostic test that is performed to detect damage or malformations of the lymphatic vessels |
| lymphedema lymph/dema | is swelling due to an abnormal accumulation of lymph fluid within the tissues lymph/ means lymph -edema / means swelling |
| primary lymphedema | is a hereditary disorder to malformation of the lymphatic system can appear anytime in life produces swelling in the feet and legs |
| secondary lymphedema | caused by damage to the lymphatic system that most commonly produces swelling in the limb nearest to the damaged lymphatic vessels; cancer treatment,trauma, radition |
| immune system | primary functions is to maintain good health and to protect the body from harmful substances |

| antigen | any substance that the body regards as being foreign; viruses, bacteria, toxins, transplanted tissue. the immune system immediately responds to any antigen |
