Lymphatic and Immune Systems

QuestionAnswer
Clear watery fluid that surrounds body cells and flows in system of lymph vessels throughout the body. Originates in bloodRich in WBC lymphocytes and monocytes LYMPH
What flows in lymph capillaries and vessels Lymph
liver, spleen, thymus and nodes Lymphatic Organs
Transports proteins and fluid that have leaked back to the bloodstream Lymphatic System Functions
Protect the body by mounting a cellular attack on foreign cells and organisms Lymphocytes and monocytes
Begin at spaces around cells throughout the body and are THIN-WALLED tubes Lymph capillaries
Carry lymph from tissue spaces to larger lymph vessels Lymph capillaries
Have THICKER walls than those of lymph capillaries. contain valves so lymph flows in only 1 direction. Lymph Vessels
Lymph vessels flow in what direction? TOWARD THORACIC CAVITY
Located in lymph nodes as well as in the spleen, liver and lungs, they phagocytose (swallow) foreign substances MACROPHAGES
Produce antibodies B Lymphocytes (B Cells)
Attack bacteria and foreign cells T Lymphocytes (T Cells)
What is in the cervical, axillary (armpit) mediastinal, and inguinal regions of the body? LYMPH NODE CONCENTRATION
Enlarged lymph tissue in the part of the throat near the nasal passages (nasopharynx) ADENOIDS
This organ NOT essential to life, and located in the left upper quadrant of the abdomen, next to the stomach SPLEEN
dESTROYS OLD RED BLOOD CELLS, FILTERS MICROORGANISMS AND OTHER FOREIGN MATERIAL OUT OF THE BLOOD SPLEEN
Stores blood, especially erythrocytes and platelets SPLEEN
Located in the upper mediastinum between the lungs. THYMUS GLAND
Provides immunity in fetal life and in early years of growth THYMUS GLAND
Early in development, in the thymus, lymphocytes learn to recognize and accept the body's own antigens as "self" or friendly. This is known as? TOLERANCE
Specialized to defend the body against antigen such as toxins, bacterial proteins, or foreign blood cells. IMMUNE SYSTEM
The body's ability to resist foreign organisms and toxins that damage tissues and organs IMMUNITY
Genetic predisposition, Inhereted and present at birth to fight off infection with "NO PRIOR EXPOSURE" TO antigens NATURAL IMMUNITY Phagocytosis Macrophages Natural Killer Cells (NK)
by contracting a disease, by vaccination, or stem cell transplant Having an infection ACQUIRED IMMUNITY ACTIVE
Only active for a certain amount of time, antitoxins, antibodies from mother Immunoglobins ACQUIRED IMMUNITY PASSIVE
These originate from bone marrow stem cells and produce antibodies when exposed to specific antigens: viruses, bacteria T CELLS
Originate from stem cells in the bone marrow, but are processed in the thymus gloand with thymic hormones T CELLS
When ______ encounters an antigen, it multiplies rapidly to produce specific types of cells that destroy the antigen T CELL
____ is the use of antibodies, B cells and Tcells treat disease such as cancer IMMUNOTHERAPY
____ Antibodies created in a laboratory cloning technique, designed to attack specific cancer cells MONOCLONAL ANTIBODIES (MoAb)
Antigens from tumor cells, May be injected or given as a nasal spray VACCINES
In ______ , T lymphocytes from a donor can replace a patient's immune system with new cells that recognize tumor cells as foreign and kill them TRANSFER OF IMMUNE CELLS BONE MARROW TRANSPLANTATION
Lymphocyte that originates in the bone marrow and transforms into a plasma cell to secrete antibodies HELPER T CELL
Which is the formation of antibodies and lymphocytes after exposure to an antigen? ACQUIRED IMMUNITY
protection IMMUN/O
lymph node LYMPHADEN/O
again, anew ANA-
armpit AXILL/O
Formation of a cell -CYTOSIS
protein -GLOBULIN
enlarge MEGALY-
Resembling -OID
deficiency -PENIA
protection -PHYLAXIS
formation -POIESIS
TO SET; PERTAINING TO STANDING OR POSITIONED -STITIAL
to stop -SUPPRESSION
What is the formation of lymph? LYMPHPOIESIS
Interstitual fluid is. FLUID THAT SURROUNDS BODY CELLS
Pertaining to poison TOXIN
A node is COLLECTION OF STATIONARY LYMPH TISSUE
Name 2 locations of lymph tissue that will increase its size with infection TONSILS, AXILLARY, INGUINAL, CERVICAL
Where are the adenoids located? IN NASOPHARYNX
Where are the tonsils located and what is the function of a tonsil? IN THE BACK OF OROPHARYNX FILTERS AIR, TRAPS BACTERIA
What is the name of the organ near the stomach that produces and stores and eliminates worn out RBC SPLEEN
What are helper T cells? A LYMPHOCYTE THAT AIDS B CELLS AND T CELLS IN RECOGNIZING ANTIGENS AND STIMULATE ANTIBODY PRODUCTION
What is the purpose of a vaccine and name different types of immunity. CONTAIN ANTIGENS THAT STIMULATE T CELLS TO RECOGNIZE AND KILL CANCER CELLS. NATURAL IMMUNITY (inhereted and thr @ birth)no prior exposure ACQUIRED IMMUNITY (vaccinations)after infection T and B cells
