(22 cards)

Acquired immunodeficiency syndrome (AIDS)

Front

Is caused by a virus A disease in which the immune system is weakened

Back

Humoral resoponse

Front

Pathogens in lymph (B lymphocytes or B cells are used)

Back

Autoimmune diseases

Front

The immune system loses tolerance for self and turns against certain molecules of the body doesn't recognize normal body structures so makes antibodies to attack them ex: scoliosis

Back

Acquired immunity

Front

Immunity that is developed during a person's lifetime Formation of antibodies and lymphocytes after exposure to an antigen

Back

Primary immune response

Front

B cell and T cell activation after first encounter with an antigen The initial immune response to an antigen

Back

Patrolling cells

Front

White blood cells

Back

Allergens

Front

Antigens that cause exaggerated responses (allergies)

Back

Mast cells

Front

Release histamine when you get injured

Back

Active immunity

Front

Immunity that develops as a result of natural or deliberate exposure to an antigen

Back

Histamine

Front

A chemical that is responsible for the symptoms of an allergy

Back

Innate immunity

Front

Present before any exposure to pathogens and is effective from the time of birth (nonspecific responses, external barriers, and cellular/chemical defenses)

Back

Passive immunity

Front

Temporary immunity that develops as a result of natural or deliberate exposure to an antibody Mother to child

Back

Macrophages

Front

large white blood cell found in tissue or mobile at sites of infection

Back

Antihistamines

Front

Decrease allergy symptoms by blocking histamine receptors Medicines that reduce the production of histamines

Back

B-cells

Front

Attack, learn, and remember pathogens that are circulationg in the blood and lymph, matures in bone marrow a white blood cell that make antibodies

Back

T-cells

Front

Cells created in the thymus that produce substances that attack infected cells in the body.

Back

Cell mediated

Front

Pathogens in cells (uses Cytotoxic lymphocytes)

Back

Barriers

Front

Structures that prevent the pathogens ( Mucus membranes and the acidity of skin)

Back

Secondary immune response

Front

Memory cells facilitate a faster, more efficient response response to an antigen by memory B cells and T cells

Back

White blood cells

Front

Blood cells that perform the function of destroying disease-causing microorganisms Destroys pathogens (bacteria) in the body and cleans wounds to maintain health

Back

Antigens

Front

Foreign molecules or bad cells

Back

Fever

Front

Inhibits bacterial growth, stimulates phagocytosis, speeds up repair of tissues, and causes the liver and spleen to store iron

Back
