Immune System

Any organism that causes disease like a virus or bacteria is called:

• Antibiotics

• Antibody

• Pathogen

• Phagocyte

A white blood cell that destroys pathogens by engulfing them and breaking them down is called:

• B-cell

• Phagocyte

• Antibody

• Antigen

Part of the body's defense against pathogens in which cells of the immune system react to each kind of pathogen with a defense targeted specifically at that pathogen is called:

• Protective Barrier

• Inflammatory Response

• Immune Response

• Stomach acid

A molecule that the immune system recognizes either as part of the body or as coming from outside the body:

• Antigen

• Antibodies

• Antibiotics

• Antipaths

A protein produced by B cells of the immune system that destroys pathogens is called:

• Antigens

• Antibodies

• T-cells

• Lymphocytes

The body's ability to destroy pathogens before they can cause disease is called:

• Tolerance

• Immunity

• Vaccine

• Inflammatory response

The process by which harmless antigens are introduced into a person's body to produce active immunity is called:

• Vaccination

• Immunity

• Passive Immunity

• Protective Barrier

Immunity in which antibodies are given to a person rather than produced within the person's own body like with a baby and mother.

• Passive Immunity

• Active Immunity

• Vaccination

• Inflammatory response

Immunity that occurs when a person's own immune system produces antibodies in response to the presence of a pathogen like with a vaccination.

• Passive Immunity

• Active Immunity

• Inflammatory Response

• Protective barrier like your skin

What is a function of the IMMUNE system?

• To transport materials like oxygen to our cells

• To break down food and absorb the nutrients

• To fight off diseases with white blood cells

• To control the body using the brain
