What is the name of the major artery supplying the head, face, and neck?

The major artery responsible for supplying blood to the head, face, and neck is known as the carotid artery. This artery branches from the aorta, the body's main artery, and bifurcates into the internal and external carotid arteries. The internal carotid artery supplies blood to the brain, while the external carotid artery supplies blood to the face and neck structures, making it essential for providing oxygen and nutrients to these areas. Understanding the function of the carotid artery is crucial in skincare and medical practices, as it plays a significant role in overall circulation and health of facial tissues.
