Immun

A small injected dose of a pathogen that stimulates the production of antibodies is:

• histamine
• interferon
• pathogen
• vaccine

An organism that enters a life form and causes disease or sickness is a/an:

• macrophage
• pathogen
• vaccine
• flu

The first line of localized defense of the immune system is:

• lymphatic response
• infection response
• auto-immune response
• inflammatory response

This refers to the type of immunity developed from exposure to a pathogen:

• active acquired immunity
• passive acquired immunity
• innate immunity
• attenuated immunity

A type of cell that "digests" pathogens is known as a/an:

• helper T cell
• macrophage
• suppressor T cell
• plasma cell

This gland, located anterior to the heart, but posterior to the sternum, is the lymphatic site where T cells are produced and mature:

• tonsils
• trachea
• thymus
• thalamus

A type of T cell that destroys infected cells is a:

• cytotoxic T cell
• helper T cell
• memory T cell
• suppressor T cell

The organism that is infected by a pathogen/antigen is known as the:

• survivor
• infectee
• source
• host

This reaction may cause sneezing, watery eyes, and cough in response to a foreign substance:

• immune response
• allergic response
• interferon response
• None of the above responses are correct

Virus replication may be slowed down by the natural production or administration of this signaling protein:

• interferon
• histamine
• plasma cell
• antibodies
