Immune system's ability to distinguish its body's cells.
What is Self Recognition?
100
Cell surface markers that help the immune system identify them.
What is an Antigen?
100
Reproduction of an activated lymphocyte so there are many copies.
What is Proliferation?
200
Skin, mucous membranes, digestive system, respiratory system and reproductive system.
What are Physical Barriers?
200
Smallest vessels of the Lymphatic System. Located in-between blood capillaries and other cells that process and drain interstitial fluid.
What are Lymph Capillaries?
200
Immune system's ability to distinguish cells that do not belong in its body.
What is Non-self Recognition?
200
Proteins secreted by plasma cells (B lymphocytes) that attack infected cells.
What is an Antibody?
200
Process by which cells assume different shapes and functions to different parts of the body.
What is Differentiation?
300
Tears, saliva, digestive juices, urine, mucous secretions and sweat.
What are Chemical Barriers?
300
Valved vessels that carry lymph through the body.
What are Lymph Vessels?
300
Nonspecific defense mechanism, the body's first line of defense.
What is Innate Immunity?
300
Phagocytic WBC's that are first responders of inflammatory response. Involved in innate immunity. (polymorphonuclear granulocyte)
What is a Neutrophil?
300
"Waking up" of lymphocytes to fight a pathogen.
What is Lymphocyte Activation?
400
Disease in which the immune system attacks and destroys healthy body tissues.
What is an Autoimmune Disorder?
400
Blobs of lymphoid tissue located along lymph vessels, filtering and destroying invading microorganisms.
What are Lymph Nodes?
400
Specific defense mechanism. Learns and recognizes invaders from previous exposure.
What is Adaptive Immunity?
400
White blood cell responsible for much of the body's immune system, antibody production, cellular immune response. (Mononuclear agranulocyte)
What is a Lymphocyte?
400
Released by basophils, associated with allergic reaction. Produces redness and swelling.
What is a Histamine?
500
Recycle fluids, transport pathogens, storage and maturation of WBC's, absorb glycerol and fatty acids.
What is the Function of the Lymphatic System?
500
Body system that includes lymphatic vessels, lymph nodes, lymph fluid and lymphoid tissues, lymph organs and the blood cells; lymphocytes and macrophages.
What is the Lymphatic System?
500
System and process of the body protect itself agains disease.
What is the Immune System?
500
White blood cell: Immune defense with macrophages and dendritic cells. (Mononuclear cell, agranulocyte)
