@wonderofscience One question, tho. How does the bacterium "know" it's being chased? In fact, is the white blood cell really chasing the bacterium? Or just following a trail of something? Are they sensitive to touch? How does the white cell determine that it has to eat something?
@yuki2501 @wonderofscience Looks like the bacteria is just being pushed away, it doesn't know it's being chased and doesn't flee.
