Which of the following arteries provides blood to the lower lip?

The inferior labial artery is specifically responsible for supplying blood to the lower lip. This artery branches off from the facial artery, which itself serves a broader area of the face. The inferior labial artery ensures that the lower lip receives the necessary blood supply for proper function and health.

In contrast, while the superior labial artery does supply blood to the upper lip, it does not serve the lower lip. The angular artery is a continuation of the facial artery that primarily supplies the area around the medial canthus of the eye and does not specifically target the lips. Finally, while the facial artery plays a significant role in the vascular supply of the face, it is not the artery that delivers blood exclusively to the lower lip; that function is designated to the inferior labial artery.
