It's all moving outwards. This is very obvious in any animated images, as from SOHO. The only plasma that falls back onto the Sun is what is trapped in tightly closed magnetic fields, which are very close to the surface at the scale of this image. Of course, we have a variety of space-borne sensors monitoring solar wind and solar radiation, and it's all moving away from the Sun. As you'd expect, of course, given that there are no forces present to produce motion in the opposite direction.
Sorry didn't mean inwards. I'm not sure you are right. I have seen videos that show electrons moving in towards the sun through the outward moving solar wind. Further the solar wind is obviously moving outward to very high latitudes. The three dimensional image reduced to two dimensions in a video would show solar wind moving north from the pole even if not emitted from 85-90 degrees N Lat. It appears as if the corona is different in character at the polar regions from the remainder of solar emissions this is pretty interesting, why.
