The external carotid arteries branch out into the maxillary arteries. They further supply the mandibular (inferior alveolar) arteries, which enter the mandibular foramina on the medial sides of the mandibles and then course rostrally in the mandibular canals, where they exit through the mental foramina. The maxillary arteries also give rise to the major palatine arteries, which anastomose with the infraorbital arteries. The infraorbital arteries exit at the infraorbital foramina to supply the rostral muzzle. The lingual artery, a branch of the external carotid artery, supplies the tongue and mucosa of the floor of the oral cavity. The mandibular canal contains the inferior alveolar artery, vein, and nerve (the neurovascular bundle).

Lymph from the oral cavity drains into the parotid, mandibular, lateral, and medial retropharyngeal, superficial, and deep cervical lymph nodes. The mandibular lymph nodes are located rostral to the mandibular salivary gland. They are not lobulated like the salivary gland and therefore can be distinguished from them. They, along with the parotid lymph nodes, drain the entire head. They are more superficially located than the parotid lymph nodes and therefore are more easily palpated.
