4.01 Lymphatic Sys.
NC Health Science I Lymphatic System
| Term | Definition |
|---|---|
| Lymph Fluid | Straw Colored, goes between capillary blood & Tissues; Helps with Fluid Balance |
| Lymphatic Vessels | Carries Lymph fluid; Parallels veins; Flows in only one direction; Drains in larger lymphatic vessels |
| Thoracic Duct | Largest Lymph Vessel, Drains from left upper body, & all of lower body |
| Drains lymph from right head, neck, chest and arm | |
| Lymph Nodes | Tiny oval shaped, located all over the body, produce lymphocytes, filters our harmful substances, can become inflammed |
| Tonsils | Masses of lymphatic tissue that produces lymphocytes & filter bacteria; 3 sets=palatine, lingual, pharyngeal |
| Palatine Tonsils | located in the back of the throat |
| Lingual Tonsils | Located at the base of the tongue |
| Pharyngeal Tonsils | AKA adenoids, located in the nasopharynx |
| Thymus Gland | Produces lymphocytes, located in upper chest, anterior to the heart, most active during younger age |
| Spleen | Located in the left upper quadrant of the abdomen, produces lymphocytes, filters blood, stores blood, destroys old RBCs |
| Fluid Balance | Function of the Lymphatic System; fluid diffuses out of blood, enters lymphatic system with waste, vessels carry it back to the 2 big lymphatic vessels |
| Lymphocyte Production | Function of the Lymphatic System; Lymphocytes travel through the lymphatic system, they are activated by viruses, bacteria or other substances, they respond by making antibodies |
| Filtration | Function of the lymphatic System; Lymph nodes act as filters by detecting bacteria, viruses or other foreign substances |
| Immunity | Function of the lymphatic system; The body's ability to resist disease; There are multiple types |
| Natural Immunity | Immunity that you are born with; skin, eye lashes |
| Passive Acquired Immunity | Antibodies are given to the patient |
| Naturally Acquired Immunity | Patient gets the illness, recovers from illness, builds antibodies to illness |
| Artificially Acquired Immunity | Patient gets the vaccine for illness, builds antibodies to illness |
| Anaphylactic Shock (severe allergic reaction) | –overreaction of the immune system to allergen; –Coughing, wheezing, hives, trouble breathing, swollen throat; –Rx–EpiPen |
| Cancer | –Abnormal growth of cells; –carcinoma, lymphoma, leukemia, sarcoma; –Tx–Surgery, chemo, radiation |
| HIV/AIDS | –Human Immunodeficiency Virus (HIV) causes Acquired Immunodeficiency Syndrome (AIDS); –pt could be positive without showing symptoms; –Tx–based on symptoms, Antiretroviral meds |
| Hodgkin's Disease | –Lymphoma, lymphocytes begin to multiply; –Painless swelling of the lymph nodes; –Tx–Chemotherapy & radiation |
| Infectious mononucleosis | –Epstein–Barr Virus (EBV) passed through body fluids, especially saliva; –Fever, fatigue, sore throat, swollen lymph nodes; –Tx–Rest, fluids, medications for pain & swelling |
| Lymphedema | –Too much lymph fluid, swelling, damaged or blocked lymphatic system; –Swelling usually in one extremity; –Tx–Compression devices, massages |
| Tonsilitis | –Bacterial or viral infection, streptococcus ; –Throat pain, red tonsils, swollen glands in neck; –Tx–Antibiotics for bacterial; tonsilectomy |
| Autoimmune disorders | –Body's immune system attacks itself; –Early s/s similar; individual dx have own symptoms; –Tx–no cure, medications can help with inflammation |
| Lupus erythematosus | –Autoimmune disease; –fatigue, achy muscles, swelling; butterfly shape rash on face; –Tx–Anti–inflammatory drugs |
