Which artery is responsible for facial flushing by bringing more blood to the face?

• A. Facial Artery
• B. Superior Temporal Artery
• C. Internal Carotid Artery
• D. External Carotid Artery

Answer: (A)

Facial flushing happens when the skin’s blood vessels widen and more arterial blood reaches the face. The artery that directly supplies the facial tissues—cheeks, lips, nose, and surrounding muscles—is the facial artery. It travels along the jaw and cheek, delivering blood right to the areas that become flushed. The other vessels have different roles: the superior temporal artery mainly serves the scalp/temple region, the internal carotid artery feeds brain and eye structures, and the external carotid artery is the larger trunk that gives off many facial branches but doesn’t by itself specify the facial surface as clearly as the facial artery. So the facial artery is the best fit for bringing more blood to the face and causing flushing.
