How hard is external carotid artery to cut?

Well, from what I've read, the arteries are "elastic" meaning it's thick and at the same time, hard to tear or cut. Like it can be squeezed and it won't pop? I don't know though, since I'm not a doctor, I'd ask a doctor. Do you have a cut artery?? They said those things are emergencies so please do not wait when it comes to your health! Good luck! All the best.
