How Do They Relate to Pathogens?
An antigen is a naturally-occurring substance that is found on the surface of pathogens. As pathogens travel around, they would accidentally leave bits and pieces of antigens behind, which would serve as clues for our bodies’ defenders (such as white blood cells) to know that a dangerous invader has come into the body.

What Kind of Science Does this Comic Teach?
⇒Topic: Antigen Definition (What Are Antigens?)
Pathogens are microscopic organisms that can cause illnesses and can spread from person to person (contagious).
Proteins are a type of organic molecules that consist of amino acids. It is frequently found in living things.
Carbohydrates are a type of organic molecules frequently found in living things. Examples of carbohydrates are sugars, starches, fibers…etc.
