The venous drainage of the head and neck follows a path quite similar to that of the blood supply, originating from three main sources and ending in the internal and external jugular veins.
Description
The venous drainage of the head and neck begins from three main venous systems:
- Intracranial: Cerebral veins (sinuses)
- Superficial veins
- Deep veins
These sources form the two main veins of the neck — the internal and external jugular veins. These veins drain all of the blood from the head and neck and are somewhat comparable to the internal and external carotid arteries.
The schematic drawing below demonstrates the path and relation of these groups of veins.
