eli5: how come when someone gets cut in the neck, blood comes out like it’s from a hose and people faint quickly? Does blood travel fast in that area?

Your heart is a big ass pump. The biggest hose/pipeline that comes out of that pump goes right to your brain via your neck. Think of it as a water main, compared to a hose that gives water to your sink. It is high volume and high pressure, right out of the pump.
If you cut that, you are in deep shit for 2 reasons. 1, That pump is moving a lot of liquid (blood) and cutting the water main will make you lose a lot of blood fast. 2. Your brain needs a lot of fresh blood, and when that flow stops, or that pressure drops, you pass out.
Cutting you jugular or carotid artery usually will mean you pass out inside 10 seconds, and can be dead shortly there after.
