Ch 37: Immune System
Terms in this set (49)
agents that are the cause of infectious disease.
a disease caused when a pathogen is passed from one organism to another; disrupting homeostasis in the organisms body.
states that some microorganisms are pathogens.
rules for demonstrating that an organism causes disease
source of the pathogen in the environment; a way to spread a pathogen.
an individual that is symptom free but is capable of passing the pathogen.
Pathogens are transmitted 4 ways
direct contact, indirect contact through objects & air, and vectors.
found in small amount within the population. (common cold)
a disease that has a large break out in an area that effects many.
a disease that effects everyone through a country continent, or globe
a substance that can kill or inhibit the growth of other microorganisms
protects the body from any pathogen it encounters; first line of defense.
used by the body to protect against pathogens
Chemical & Skin Barriers
layers of dead skin cells covering layers of living skin cells.
saliva tears, nasal secretions, mucus, and hydrochloric acids.
blood cells that ingest bacteria
cells of the immune system defend the body
blood cells that ingest bacteria and remove dead neutrophils and other debris.
process by which cells surround and internalize foreign microorganisms; release phagocytes.
enhance phagocytosis by helping phagocytes bind better to pathogens, activating the phagocytes and enhancing the destruction of pathogen's membrane.
a cellular defense that helps the virus from spreading when it enters the body; binds to neighboring cells and stimulates these cells to produce antiviral proteins.
a series of events that involves many chemicals and immune cells that help enhance the overall immune response. (pain, heat, redness)
involves the tissues and organs; second line of defense.
included organs and cells that filter lymph & blood, and destroys foreign microorganisms; absorbs fat.
fluid that leaks out of capillaries to bathe the body's cells
lymphatic system contains lymphatic tissue, lymphocytes, and connective tissue. (lymph nodes, tonsils, spleen, thymus gland, diffused lymphatic tissue.)
a type of white blood cell that is produced in the red bone marrow and produces antibodies and other chemicals.
filter lymph and remove foreign materials from the lymph.
produced in the bone marrow but mature in the thymus gland. (located above heart)
protein produced by B-Cells, that react with foreign antigens.
a substance foreign to the body that causes an immune response; can bind to an antibody or T-Cell.
located in all lymphatic tissues and can be thought as "Antibody Factories."
activates antibody secretion in B-Cells and another type of T-cell, that aids in killing foreign microorganisms.
Immune system Failure
defects in the immune system increase likelihood of developing infectious disease & types of cancer.
diseases caused by inheritance of genes that are defected; albinism, sickle cell anemia, huntington disease, hemophilia, and down syndrome (chromosomal disorders.)
result of a part of the body wearing out. (arthritis)
result from error in biochemical pathway.
abnormal cell growth that can develop in any organ or body tissue.
allergies and autoimmunity.
a response to an environmental antigen
the antigens that trigger an allergy. (pollen, dust, & various foods.)
a chemical released by certain white blood cells; symptoms of allergens are the result of this chemical.
form antibodies to their own proteins which injures their cells. (Rheumatic disorder & Lupus)
a type of T-Cell that helps try to stop an immune response by releasing signals to other immune cells.
A severe allergic reaction to a certain allergen which causes a massive release oh histamine.
Destroy pathogens and release chemicals (cytocines)
The body's first reaction to a pathogen
Long living cells that are exposed to the antigen during the primary response; remember disease and decrease the chance of getting the disease again.
Occurs after the immune system is exposed to the diseased antigens; memory T-Cells are produced.
Vaccination; provide future protection from the disease causing organisms; exposure of the body to the antigen so that primary response and memory cells are produced.
