Our bodies are constantly under threat of invasion. Given free reign, the enemy will infect, infiltrate and destroy us all. Only the immune system stands in the way, the first and last line of defence.
Who stops those ignoble viruses?
The immunoglobulins, searching throughout your body with constant vigilance...looking for the enemy. Each antibody is specific for just one type of enemy. There are five classes of immunoglobulins, the main one is IgG. It's the smallest, sneakiest of the antibody ninjas.
How long can you last before infection takes over???
Tap the left side of the screen to switch the left and middle antibodies - tap the right side to switch the right and middle. Seems too easy? Try not to get confused...
