I've been wondering about something. Blood flows through your veins and arteries, right? So when say, you cut yourself and you bleed, does this mean that you've also cut into a vein/artery? Or does blood freely flow around everywhere as well as through veins and arteries?

It depends on the size/depth of the cut. Generally the blood comes from capillaries in minor cuts and grazes. But if the cut is deeper, then blood could originate from vein or artery, which could be more dangerous. A ruptured major vessel could easily be fatal.

Okay so don't quote me on this but I know you have capillaries which are much smaller than veins and arteries so I'm guessing that's what you cut, there are lots of them and they are directly beneath the skin. Capillaries also can burst when the skin is hit, which makes a bruise. (Come through GCSE Biology!) A vein or artery would be a lot more dangerous and have more blood than just a small cut on your finger or something like that.
