According to the research, the statement is true. Venous drainage of the head and neck is through the internal jugular vein, which then drain into the brachiocephalic veins.
<h3>What is the internal jugular vein?</h3>
It is a very wide and thick duct that it is responsible for collecting the non-oxygenated blood that comes from the head, from the anterior area of the neck.
Being the largest caliber and the other jugular veins flow into it; it is a continuation of the sigmoid sinus and together with the subclavian vein made up of the brachiocephalic veins that drain blood from the head, neck, and upper extremities.
