The facial artery is a major blood vessel that supplies oxygenated blood to the face. It branches off from the external carotid artery and travels across the jawline, providing blood to various facial structures, including the lips, nose, and cheeks. This artery is important for maintaining the health of facial tissues and plays a role in various medical procedures. Its location makes it significant in cosmetic surgeries and dental practices, as well as in understanding conditions related to facial circulation.
