Verified step by step guidance1
Understand the anatomy of the venous system in the neck and upper thorax. The external jugular vein is a superficial vein that collects blood from the scalp and face.
Identify the pathway of the external jugular vein. It descends along the side of the neck, superficial to the sternocleidomastoid muscle.
Recognize that the external jugular vein does not drain into the internal jugular vein, as they are separate venous systems.
Consider the location of the subclavian vein, which is located beneath the clavicle and is a continuation of the axillary vein.
Conclude that the external jugular vein drains directly into the subclavian vein, as it joins the subclavian vein near the base of the neck.
