Subsequently, one may also ask, is there a main artery in your nose?
The nose has a rich vascular supply, with substantial contributions from the internal carotid artery (ICA) and the external carotid artery (ECA). The ECA system supplies blood to the nose via the facial and internal maxillary arteries. The superior labial artery is one of the terminal branches of the facial artery.
One may also ask, what is the anatomy of the nose? The external nose consists of paired nasal bones and upper and lower lateral cartilages. Internally, the nasal septum divides the nasal cavity into a right and left side. The lateral nasal wall consists of inferior and middle turbinates and occasionally a superior or supreme turbinate bone.
Just so, why is there a dense blood supply in the nose?
The nose has a very rich vascular supply – this allows it to effectively change humidity and temperature of inspired air. The nose receives blood from both the internal and external carotid arteries: Internal carotid branches: Anterior ethmoidal artery.
Where are the blood vessels in the nose?
The nose contains many blood vessels, which are located close to the surface in the front and back of the nose.
