Re: Today
I believe they're speaking of blood drainage. In accidents such as this, veins are severed very easily, since they're close to the surface of the skin. Arteries are buried deep in the body, so they aren't severed nearly as easily.
What happens is blood can flow to the area, but not out of it. So, it builds up. They then have to drain the nasty old blood away, so fresh oxygen-rich blood can continue to flow.
BTW. This is the medical use for leeches. Instead of an incision, and a large drainage tube, leeches are placed on the area to be drained. They have to advantage of anti-coagulating that immediate spot, yet their bite wound is small, minimizing additional trauma.
