Immune System

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

• Antibiotics

• Antibody

• Pathogen

• Phagocyte

• Protective barrier

• Inflammatory response

• Immune response

• Stomach acid

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:

• Inflammatory Response

• Immune Response

• Stomach acid

White blood cells that distinguishes between each kind of pathogen is called:

• Lymphocyte

• Phagocyte

• Antibodies

• Antigen

A lymphocyte that identifies pathogens and distinguishes one from another:
