The angular artery is responsible for supplying blood to which area?

The angular artery is a crucial vessel that branches from the facial artery and is primarily responsible for supplying blood to the side of the nose. It specifically provides blood to the tissues in that region, enhancing both the health and appearance of the skin and underlying structures. Its position and distribution make it vital for maintaining the vascular supply to the area around the nasal region, where fine features and delicate tissues are present.

The other choices represent areas supplied by different arteries. The chin typically receives blood from the mental artery, the forehead is supplied by the frontal branches of the ophthalmic artery, and the upper lip is mostly perfused by the superior labial arteries, which are also branches of the facial artery. This anatomical understanding is essential for estheticians, especially when considering procedures that involve these facial areas.
