We just learned that the Common Carotid Artery brings oxygenated blood up to the neck, and splits into two tubes, and one of them is the internal carotid artery which brings blood to your brain.
The other artery is the external carotid artery.
This artery gives blood to all the other parts of your head, your ears, eyes, nose, mouth, tongue, teeth and skin.
