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?

Those are your jugular veins. They’re the main entry and exit road of blood to and from your brain, and their importance is shown during one of these injuries. With no blood coming through those veins (on each side of your neck) your brain will quickly become deoxygenated from the present blood becoming “stale”, this particular wound loses too much blood, though, so when you faint you basically just die all at the same time.

Edit: my terminology is off, refer to the reply to this made by u/v1perz53

You brain requires a lot of oxygen and such, which is all transmited via blood, so a lot of blood has to travel to your brain, which all goes via only a few veins so they are very thic with a lot of blood traceling through

The neck has the Jugular Vein which is responsible for being blood from your heart to your brain. You can also feel your pulse there. There is a lot of pressure and blood flow moving through that vein. That’s why it come out like a hose as you put it.

If I’m wrong, someone please correct me. I’m not a doctor

No, both of you are wrong, it’s because there’s only blood there, and the neck is like a blood station, and it has a connectivity of Bluetooth 6.0 so the neck is the Bluetooth station for the whole body to receive Bluetooth blood

Blood only takes 60 seconds to travel through your entire body, but speed isn’t shat causes the squirting, it’s the pressure. Your brain needs a lot of oxygen and nutrients, so as a result it gets a lot of blood. Your head is also above your heart, so your heart has to do a lot of work to get the blood up there, which means a lot of force (pressure) pushing the blood up into the neck. When there’s a hole for the blood to escape, instead of the blood going up to the brain, it goes out the hole.
