where is your carotid artery located in your neck

Common Causes

The vertebral arteries divide into four segments based on where they are within the spinal column:

• V1 (pre-foraminal) arises from the subclavian artery. It runs behind the carotid artery, which is also in the neck.
• V2 (foraminal) travels alongside vertebral veins and nerves. ...
• V3 (extradural or extraspinal) curves and twists across the top of the C1 vertebra (the atlas) until it enters the skull.
• V4 (intradural or intracranial) enters the skull. ...

How to cut a carotid artery?

If your own, just cut from the outside, low down, and don’t go too deep. Oh, and do it standing up. Where you’d want to cut is below your mouth, so gravity will help keep you from choking. As long as you don’t get the trachea when you cut the carotid (stay lateral!), your airway will stay nice and clear while your blood volume drops. Once you faint from blood loss, though, you may lose those protective airway reflexes and aspirate some. Thus, I’d recommend wearing some kind of respirator just to be sure no blood gets in there once you’re unconscious.

What would happen if your left carotid artery was completely transected?

If your left carotid artery were completely transected and you were nowhere near a hospital, you would die pretty quickly. Here is a rough calculation. Your cardiac output is about 5L/min. Roughly 20% of that goes to your carotids, so 10% each. So your left carotid sees a flow of about 500mL/min. At that rate, you would have no blood left in 10 minutes. Obviously that flow would not stay constant as you continued to lose blood, but it’s a good starting point.
