Definition

Noun: The common carotid artery is a major blood vessel that runs upward through the neck on each side of the body. It is the main artery that supplies oxygenated blood to the head, neck, and brain. It typically divides into two branches: the internal carotid artery (which supplies the brain) and the external carotid artery (which supplies the face and neck).

Usage Examples

  • (The artery is temporarily blocked to control blood flow.)

Advanced Usage
