The right lymphatic duct, also called the right thoracic duct, is about 1.25 cm long. It drains lymphatic fluid from the right thoracic cavity (this is the section of the trunk on the upper right side), the right arm, and from the right side of the neck and the head. In some people, it also drains lymph from the left lung's lower lobe. This duct is located near the base of the neck, and goes along the medial border of the anterior scalene muscle at the side of the neck. In most individuals, it ends at the right subclavian vein.
