Chapter 31 Vocabulary
24
Germ Theory: proposed that specific microorganisms caused diseases.
Pathogens: disease causing agents.
Vector: anything that carries a pathogen and transmits it into healthy cells
Immune System: the body system that fights off infection and pathogens.
Phagocyte: a cell that destroys pathogens surroundings and engulfing them.
T cells: destroy body cells that are infected with pathogens.
B cells: produce proteins that inactivate pathogens that have not yet been infected a body cell.
Antibodies: proteins made by B cells.
Interferon: proteins produced by body cells that are infected by a virus.
Passive Immunity: immunity that occurs without the body’s undergoing an immune response.
Active Immunity: immunity that your body produces in response to a specific pathogen that has infected or is infecting your body.
Inflammation: a nonspecific response that is characterized by swelling, redness, pain, itching, and increased warmth at the affected site.
Antigens: protein markers on the surfaces of cells and viruses that help the immune system identify a foreign cell or virus.
Memory cells: specialized T and B cells that provide acquired immunity because they “remember” an antigen that has previously invaded your body.
Humoral Immunity: a type of immune response that depends on antibodies.
Tissue Rejection: occurs when the recipient’s immune system makes antibodies against the protein markers on the donor’s tissue.
Antiseptics: chemicals, such as soap, vinegar, rubbing alcohol, that kills pathogens.
Antibiotic Resistance: occurs when bacteria mutate so that they are no longer affected by antibiotics.
Vaccine: a substance that contains the antigen of a pathogen.
Allergy: oversensitivity to a normally harmless antigen.
Allergens: antigens that cause an allergic reaction
Anaphylaxis: a condition that occurs when the immune system releases a large amount of histamine, which causes airways to tighten and blood vessels to become porous.
Leukemia: cancer of the bone marrow.
Opportunistic Infection: an infection caused by a pathogen that a healthy immune system would normally be able to fight off.
Human immunodeficiency virus: a retrovirus that attacks and weakens the immune system.
Acquired immune Deficiency Syndrome: the final stage of the immune system decline due to HIV.
