ELI5: How do insects continue to live and function without their heads?

I just saw a video of a decapitated wasp clean it's wounds and fly away with its head. I can wrap my head around how it could  still "move" without a head but I can't figure out how it's still moving with "purpose" (such as cleaning, grabbing its head, and then flying away with it)

Unlike humans, insects do not use their head to breathe, and their brains only control a few things. They have a nervous system throughout their body controlling many functions that the human brain would. They also will not die of blood loss because their blood simply doesn't work the same, and it will clot very fast at the seperation. It will, however, only live a few days at most, because it cannot eat or drink.
