what is the immune system?
the body’s internal defense system
the body's internal circulatory system
a US government organization that helps the CDC
what is an antigen
a substance that is commonly found in the body but stimulates an immune response
a substance that is made by the body to attack foreign entities
a substance that is foreign to the body and stimulates an immune response
a substance that is made by scientists to attack foreign entities, when injected into the body
refers to substances produced by the body that the immune system does not recognize as foreign, so they do not stimulate an immune response
