Blood Supply
There is a rich blood supply to the nasal cavity. In some animals, such as dogs, the capillary beds flowing through the nasal cavity help cool the blood flow to the brain.
Blood supply comes from branches of both the internal and external carotid artery, including branches of the facial artery and maxillary artery. The named arteries of the nose are:
- Sphenopalatine and Greater palatine arteries, branches of the maxillary artery.
- Anterior ethmoidal artery, a branch of the ophthalmic artery
- Branches of facial artery supplying the vestibule of the nasal cavity.
