Lymphatic and immune systems
Question | Answer |
---|---|
What is lymph | Clear watery fliud that surronds the body cells and flows in vessels through out the body. |
lymphatic system functions | Drainage system, absorbs lipids, assists imune systems |
how do lymph nodes fight disease? | T- cells and B-cells |
T Cells | produce antibodies in response to specific antigens |
B Cells | Multiply rapidly to produce cells that destroy antignes |
Adenoids | Masses of lymph tissue in the nasopharynx area (in throat near nasel cavity) |
Tonsils | Masses of lymph tissue in the oropharynx area (the throat near back of mouth) |
Spleen | Near the stomach, composed of lymph tissue, stores and elimantes blood cells, not essiental to life |
Thymus gland | located in upper mediastinum between lungs, helps body protect it self from disese (immune) |
Phagocytes | Migrate to infection an ingest bateria |
Macrophages | move to clear dead cells after infection |
Toxin | is poison, a protien produced by certian bacteria, animals or plants |
active immunity | Reciving vaccinations, having a disease that produces anitbodies, or aquried thru a transfer of immune cells from a donor |
passive immunity | antitoxins, immunoglobulins, maternal antibodies |
immunoglobulin | antibodies that are secreted by plasma cells in humoral immunity |
vaccine | weaken or kill microoganisms to induce immunity to infection or disease |
vaccination | an introduction of altered antigens to produce an immune response and protection against disease |
Dendritic cell | an important cell of the immune system, captures antigens and presents them to t cells |
immun/o | Protection |
Lymph/o | Lymph |
Splen/o | Spleen |
Ana | Again |

cryptococcus | a yeast like fungus in lung, brian and blood infections |
toxoplamosis | a parasitice infection involving the central nerve system |
tolerance | self antigen |
immunity | the bodys ability to resist forign organisms and toxinss |
natural immunity | genetic preispostion present at birth ex. Natural killer cells, macrophages,phagocytosis |
antibody | protien produced by b cell lymphocytes to destroy antigens |
antigen | substance that the body recognizes as forign |
aquried immunity | formation of antibodies and lymphocytes after exposure to an antigen. active and passive |
tolereance | T lymphocytes learn to recoginze and accept the bodys own antigens as self or friendly |
Iga, IgD, IgE, Igm | immunoglobulins |

p.c | After meals 9post cibum) |
Peg | percutionaous endoscopic gastrostomy(feeding tube placed in stomach) |
per os | By mouth |
PE tube | ventilating tube for eardrum |
prep | prepare for |
ante | before or forward |

hemi | half |
hypo | under, deficency |
what do lymph vessels do? | lead toward the thoratic cavity and empty into 2 large ducts iin the upper chest |
what does the thoratic duct do? | drains lower body and left side of the head |
what does the right lymphatic duct do? | drains the right side of head and chest |
where does the thoratic duct and right lyphatic duct carry the lymph to? | the large veins in the neck where the lymph then enters the bloodstream |
crytococcus | a yeast like fungas in the lung brain and bloodinfections. |
toxoplasmosis | a parasitic infection involving the central nervous system |
Allergy | abnormal hypersensivity to an antigen |
atopic | hypersenitivity or allergic state |
Anaphylaxis | exxagerated or unusal hypersensivity to a forign protien or other substance |
Hodgkin disease | a maligant tumor of lymph tissue on the spleen and lymph nodes |
what are the 4 stages of hodgkin diseases? | stage 1: involves ingles lymph node stage 2: involves 2 or more sites of same side of diaghram stage 3: involves diseade in both sides of diaphram stage 4: is widespread invilving the liver, bone marrow, lung and skin |
Allergen | a forign substancce (antigen) |
HIV | Human immunodeficency virus , a retro virus that causes aids |
AIDs | Acquired immunodeficency syndrome, Caused by human immunodeficency virus |
Kaposi Sarcoma | Maligent (cancerous) condition associated with aids, arises from the lining of capillaries and appears as bluish-red skin nodules |
opportunistic infections | infectionoue disease associated with sids they occur becuase HIV infection lowers the bodys resistance and allows infection by bacteria and parasites that normally are easilly contained. |
retrovirus | RNA virus that makes copies of itself by using the host cells DNA |
Whats are some drugs used to treat AIds? | Protease inhibitor and revese transcriptase inhibitor |
