Blood vessels of the pharynx
This study unit will allow you to:
- Identify the arteries that supply the pharynx.
- Name the veins that drain the pharynx.
The pharynx is an anatomical structure with a very rich blood supply. The upper parts of the pharynx are supplied by branches of the external carotid artery, while the lower parts are supplied by branches from the subclavian artery. Other important arteries are closely related to the pharynx but do not necessarily supply it with blood. The venous drainage of this region is done through a network of pharyngeal veins that form a venous plexus.
