Immune System AP2 Flashcards
Acquired Active Immunity
person is exposed to a live pathogen, develops the disease and becomes immune
Active Immunity
introduction of immunity by infection or vaccine
Adenoids
pharyngeal tonsils
anaphylaxis
life threatening response to antigen or allergen
Antibodies
proteins that lock onto and neutralize specific antigens
Antigen
foreign substance that invades body
Artificially Acquired Active Immunity
immunity introduced by vaccine
Autoimmune Disease
results in damage to bodies own cells and the body attacking itself
B Lymphocytes
cell responsible for production of circulating antibodies
Chemotherapy
use of chemicals to treat or control cancer
Chronic Fatigue Syndrome
immune system disorder or unknown origin that causes depression, sleep disorders and lack of energy
Complement
proteins that assist in destroying bacteria,viruses and infected cells
Cortex
portion of the node that is mainly populated by lymphocytes
Germinal Centers
location where b lymphocytes reproduce
Immune Response
series of immune system attacks on organisms and substances that invade the body system
Immune System
identify abnormal cells and foreign substances and defend those that might be harmful
Immunosuppresants
medications that suppress the immune system
Infectious Mononucleosis
viral infection caused by the epsteinn-barr virus. part of herpes family
Leukocytes
larger blood cells that fight infection. Phagocytes and lymphocytes
Lymphocytes
white blood cells created in bone marrow
Medulla
middle portion of kidney.
Metastasis
cancer cells break away from original tumor and travel to other parts of body to form new tumors
Natural Immunity
inherited immunity to certain diseases
Neutrophils
most common phagocytes;primarily attacks bacteria
Oncogenes
genes controlling cell growth and multiplication
Passive Immunity
immunity acquired from an outside source that last for a short time.
Phagocytes
white blood cells that attack invading organisms
Radiation Therapy
use of high energy waves such as x-ray to damage and destroy cancer cells
Rheumatoid Arthritis
autoimmune disorder ;joints to become deformed due to inflammation
Systemic Lupus Erythematosus
systemic immune disorder where body produces abnormal antibodies that attacks its own tissue rather than organism
T Lymphocytes
cells that circulate through the lymph nodes,blood stream and lymphatics ducts and seek out infection
Thymus Gland
lymphoid tissue located in the chest,anterior mediastinum. creates infection fighting t-cells
Tonsils
pharyneal tonsils(adenoids),palatine tonsils and lingual tonsils
Trabeculae
subdivide lymph nodes into different compartments
Vaccine
contains antigen and stimulates primary response against antigen without causing symptoms of disease
