Question | Answer |
What are the functions of the lymphatic system | returning tissue fluid to blood; protecting body from foreign materials such as pathogens |
What makes up the lymphatic system | lymph (tissue fluid); lymph vessels; lymph nodes & nodules; spleen; thymus gland |
What are macrophages | reticuleoendothelial (RE) cells - phagocytize foreign materials in blood & old RBCs which forms bilirubin which is excreted by liver |
What is immunity | the ability to destroy pathogens or other foreign materials to prevent further caeses of certaininfectious diseases |
Examples of foreign materials | malignant cells; organ transplants; autoimmune diseases (lupus) |
What are "Self" antigens | are not foreign |
What are "Non-Self" antigens | cells that are recognized as foreign and destroyed (viruses, bacteria, fungi, protozoa, bacterial toxins) |
Name the gamma (immune) globulins | IgG, IgA, IgM, IgD, IgE |
What is "Passive Immunity" | antibodies acquired from another source. Ex- 1)placental transmission of antibodies (naturally); 2) antibodies in breat milk (naturally); 3) gamma globulin injections (artificially) |
What is "Active Immunity" | antibody production within ones self Ex: 1) vaccinations (artificially); 2) exposure to pathogens (naturally) [note - adaptive has memory] |
When do we stop calling a tissue fluid and call it lymph | When it enters the lymph vessels (capillaries) |
Bacteria | Do not need to enter a cell to replicate |
Viruses | Need to enter cell in order to replicate |
IgA | in saliva, mucus, tears, breast milk - protects mucous membranes on body surfaces, provides immunity for newborn |
IgG | in blood plasma - major antibody in primary and secondary responses |
IgE | produced by plasma cells in mucous membranes and tonsils - binds to mast cells and basophils causing release of histamine, responsible for allergic reactions |
"Still disease" is another name for | Juvenile rheumatoid arthritis |
Lymph tissue creates what 2 kinds of white blood cells | Lymphocytes & Monocytes |
Lymphocyte nodes and nodules are made up of lymphatic tissue which produce 2 kinds of white blood cells called | Lymphocytes & Monocytes |
If a cell is fixed is it moving or not moving | Not moving |
Fixed cells and lymph nodes & nodules that produce antibodies are called | Plasma cells |
Lymph nodes can be found around the pathways of lymph vessels and below the epithelial of all mucous membranes - True or false | False - Only Lymph NODULES are found under mucous membrane |
Fixed cells that phagocytize pathogens are called | Macrophages |
What is the mechanism called that moves lymph nodes by compression | Skeletal muscle pump |
The spleen produces 2 kinds of white blood cells which are called | Lymphocytes & Monocytes |
The macrophages of the spleen are also called a different name because they phagocytise red blood cells called | RE cells |
The macrophages of the spleen that phagocytise old red blood cells forms what compound which is excreted by the liver | Bilirubin |
T Cells are produced by what white blood cell from the thymus | Lymphocytes |
How do you define immunity | The ability to fight off pathogens now and in the the future |
Immunity develops the type of lymphocytes that become very specific to a foreign antigen - these are called what 2 kinds | T cells and B cells |
Antibodies are made up of what and can also be called what | Made up of proteins and can be called immune globulins or gamma globulins |
Antigens are chemical markers that identify a cell as one of 2 things | Self and Non-Self (foreign) |
Natural cells are identified to eliminate foreign cells by damaging what part of the foreign cell | Mucous membrane |
If you were recovering from a disease would this provide you with natural or artificial immunity and would it be active or passive | Natural; active (you make your own antibodies) |
Antibodies bind to pathogens and cause clumping called | Agglutination |
Some animal viruses do not cause diseases in people because we have what kind of immunity | Genetic immunity |
What type of immunity will last a lifetime because it is programmed into your human DNA | Genetic immunity |
Is the first antibody response slow or fast and is it in a small amount or a large amount | Slow and in a small amount |
What is the function of What is the function of the spleen in the fetus | Produces red blood cells |
What organ assumes the function of producing red blood cells after birth | Red blood marrow |
What does immunocompetence mean | Immune system is working appropriately |
Antibodies are classified based on location and function - the classifications are | IgG, IgA, IgM, IgE, IgD |
If you don't have enough T Cells because of the presence of HIV, AIDS patients are very susceptible to infections called | Opportunistic |
If you were to be tested for HIV, what 2 kind of tests would be done | Elisa (1st) and Western Blot |
What common disease causes the spleen to enlarge and the patient should be cautioned to avoid activities which could involve a blow to the abdomen and causes spleen eruption | Mono |
What virus causes Hairy Leukoplakia | Epstein Barr which is a herpes virus |
ITP is an acquired disorder that results from the deficiency of what | Platelets |
Fixed cells and lymph nodes produce what | plasma cells |
Where are lymph nodes located | where something else is attached to the body - cervical, axillary and inguinal |
where are lymph nodules located | under the mucous membrane (they are smaller than nodes) |
Fixed cells that phagocytize pathogens are called | macrophages |
Macrophages in the spleen can be called by another name which is | RE cells |
Antigens are chemical markers that identify cells as | self or non-self |
