    One of the key players of our immune system is the complement system. An army of millions and trillions of tiny bombs, which work together in a complex and elegant dance to stop intruders in your body.

    Our Complement System is super complex and fascinating and we can’t get enough of it - so we also made a poster and postcards with its core workings step by step.

    It would be cool to have a video game based on this. Like Call of Duty style where you will play as a protein and you will kill benign cancer cells, etc. There are also bosses and unlockable characters. Imagine learning while enjoying.

    I got some questions...
    Anyone can answer, dont worry.
    1.- ¿Does all Virus are bigger that cells?
    2.- This looked like only a few Virus were in human body. I dont think so because Virus are so small... ¿the inmune sistem takes more to eliminate them than this video?
