Immune System and Disease

Disease-causing microorganism, such as a bacterium or virus.

• pathogen

• allergen

• prion

• antigen

A nonspecific defensive response of the body to tissue injury characterized by dilation of blood vessels and swelling.

• immunity

• interferon

• immunization

• inflammation

Which of the following is not apart of your body’s first line of defense?

• Skin

• Mucus

• Stomach Acid

• Antibodies

This type of cell inspects intracellular for antigens and kills any cells that display the foreign antigens.

• Macrophage

• T Cells

• B Cells

What is a protein used by the immune system to neutralize pathogens?

• antigens

• macrophages

• T cells

• antibodies

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 as a foreign substance that signals molecules to induce an immune response:

• Antigen

• Antibodies

• Antibiotics

• Antipaths

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

• Tolerance

• Immunity

• Vaccine

• Inflammatory response

Which of the following is a way to spread infectious diseases?

• Touching contaminated objects

• Not washing hands regularly

• Being near infected people

• All of these are ways

When the body encounters a pathogen, antibodies are created that are specific to that pathogen. The next time the body encounters the pathogen, the response will be:

• Slower

• Faster
