Additional Information

White Blood Cells

The white blood cells are tiny blood cells that protect your body against foreign invaders.

Antigens

Proteins

Proteins are molecules consist of amino acids.  They are a key component that make up most living things.

Pathogens

Pathogens are micro-organisms that can cause an illness and are contagious, capable of spread from person-to-person.
