An antigen (from antibody-generating) is a substance that prompts the generation of antibodies and can cause an immune response The word originated from the notion that they can stimulate antibody generation. We now know that the immune system does not consist of only antibodies. The modern definition encompasses all substances that can be recognized by the adaptive immune system.

White blood cells fight bad stuff, red blood cells carry oxygen. Plasma is the liquid content in blood where the cells are suspended.
