Which artery is chiefly responsible for supplying blood to the face?

External carotid artery
Internal carotid artery
Facial artery
Maxillary artery

The correct answer is: Facial artery

The facial artery is the main vessel responsible for supplying blood to the face. It branches off from the external carotid artery and runs along the face, providing oxygenated blood to the skin and muscles of the facial region. This artery supplies important structures such as the lips, nose, and jaw, and it plays a crucial role in maintaining the perfusion and health of facial tissues. While the external carotid artery is a significant source of blood supply to the head and neck, it gives rise to multiple branches, including the facial artery, which specifically targets facial areas. The internal carotid artery primarily supplies blood to the brain, making it less relevant to the facial blood supply. The maxillary artery, another branch of the external carotid artery, supplies various deep structures of the face and jaw but does not directly serve the superficial facial regions as effectively as the facial artery does.
