Reply to comment by elevenblade in when a limb gets amputated, how do they stop the flow of blood? by EnchantedCatto

Fascinating. I guess this answers a question I've had for a long time about how amputation works. I always assumed that during, for example, a leg amputation, the arterial system was like a 1-way highway for blood that went around your body in a circle, and into your leg and back out (with various exits and off-ramps for blood to go to your tissue), and you would have to connect the two halves of the pipe system if the connection was severed. But now it seems obvious that there is no "back out", or at least not a "back out" artery. It goes from the arteries to your tissue, and then it goes out through veins, right?

It takes an off-ramp from the highway, down some streets, into the laneways, drops off it's parcel of oxygen, then makes it's way back up to another highway back to the heart.

There are loads and loads of little streets.
