Which artery is the major supply for the head, face, and neck?

The carotid artery is the primary vessel responsible for supplying blood to the head, face, and neck. It branches from the aorta and divides into two main arteries, the right and left carotid arteries. These arteries further split 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 regions, providing essential nutrients and oxygen needed for these areas to function properly. This anatomical importance confirms the carotid artery as the major supplier of blood to the head, face, and neck.

In contrast, the jugular artery primarily carries deoxygenated blood back from the head and neck to the heart, rather than supplying blood. The coronary artery supplies blood specifically to the heart muscle, and the subclavian artery primarily supplies blood to the arms and parts of the chest, playing a less direct role in supplying the head and neck regions.
