The wild boar is broadly distributed in several parts of the world by man, with the exception of Antarctica. It is known that the facial artery and its branches are responsible for maintaining the blood supply of structures related to chewing, swallowing, and the production of saliva. The aim of this study is to describe the origin and distribution of the right and left facial arteries of the boar in the context of foraging. The facial arteries of this boar species originated from the external carotid artery in all specimens and were distributed in the pharyngeal, glandular, and muscular branches as well as the branches to the mandibular lymph nodes. The anastomotic branches of the facial artery with the buccal and mylohyoid branch of the inferior alveolar artery were also identified. This feature shows that the region of allocation of the facial artery in these animals requires a large network for irrigation, which contributes to the functional efficacy as well as the modus viventis of this animal.
