Ways to tell them apart:
An antibody is like a soldier, defending the body against invaders called antigens.
Antigens can be thought of as foreign objects or enemies that label as targets for the body’s immune system.
Antibodies recognize and bind to antigens to neutralize them, like a key fitting into a lock.
The term antibody has a body in its name, indicating it is part of the body's defense mechanisms.
Antigen indicates against genesis, reflecting that it generates an immune response as it is foreign to the body.
