What would happen to a human in outer space?

Blood and other bodily fluids are pulled by gravity into the lower body. When you go to space, gravity weakens and thus fluids are no longer pulled down, resulting in a state where fluids accumulate in the upper body. This is why the face swells in space.

Can human survive in outer space?

Space is very dangerous – and without protection, people would not be able to survive there. In space, there’s no air – so you couldn’t breathe. It’s cold – so you’d freeze. And there’s lots of nasty radiation (from the Sun, and from the rest of the Universe), so you’d get really, really bad sunburn.
