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 skin, muscles, and glands. This artery is important for maintaining the health of facial tissues and plays a role in various facial functions. It further divides into smaller branches that reach areas such as the lips, nose, and cheeks, ensuring that these regions receive adequate blood flow for nourishment and healing.
