Immune System


Ability of the body to resist a particular disease. Immunity.
White blood cells that engulf foreign invaders. Phagocytes.
Foreign substances that are not supposed to be in your body. Antigens.
Disease-causing bacteria or microorganism Pathogen.
Proteins that react with a specific antigen and inactivate them. Antibodies.
True or False: The antigen-antibody complex involves using antibodies with a specific shape to match the antigen. True.
___________ _____________ ______________ have antigens present on their membrane. Red blood cells.
Reaction of the immune system to the presence of foreign cells or molecules by producing antibodies that are very specific and specialized cells that bind to and inactivate foreign substances. Immune response.
Produces T-cell lymphocytes. Thymus.
Makes red blood cells, white blood cells, and platelets. Bone Marrow.
Removes warn out red blood cells and removes, stores, and produces white blood cells. Spleen.
Immunity that develops during an individual's lifetime. Acquired immunity.
Body produces the antibodies to a particular disease either by contact with the disease organisms or by receiving a vaccine. Active immunity.
Dead or weakened form of a pathogen injected into an individual so that the body can produce antibodies to fight the foreign antigen. Vaccine.
Antibodies from an outside source that are introduced into the individual's blood. Passive immunity.
True or False: Passive immunity involves permanent immunity. False, the immunity is temporary.

Six examples of first-line defenses. Skin, sweat, tears, membranes, mucus, and stomach acid.
Two examples of second-line defenses. Inflammatory response (swelling and redness) and macrophages that engulf bacteria.
Recognizes the antigen on the cell's surface, the cell divides and creates killer _________ __________ and memory cells. T-cells.
Gets stimulated by helper t-cells that recognize the antigens, undergoes cell division, producing plasma cells and memory cells, plasma cells make antibodies that are released into the blood and bind to the antigen, phagocytes come and destroy complex. B-cells.
