Lymphatic (immune)


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
