where does the thoracic duct drain lymph from
Thoracic duct In adults, the thoracic duct is typically 38–45 cm in length and has an average diameter of about 5 mm. The vessel usually starts from the level of the twelfth thoracic vertebrae (T12) and extends to the root of the neck. It drains into the systemic (blood) circulation at the angle of the left subclavian and internal jugular veins as a single trunk, at the commencement of the brachiocephalic vein.[1][2] It also collects most of the lymph in the body other than from the right thorax, arm, head, and neck which are drained by the right lymphatic duct.[3]
Thorax The thorax or chest (from the Greek θώραξ thorax "breastplate, cuirass, corslet"[1] via Latin: thorax) is a part of the anatomy of humans and various other animals located between the neck and the abdomen.[2][3] The thorax includes the thoracic cavity and the thoracic wall. It contains organs including the heart, lungs, and thymus gland, as well as muscles and various other internal structures. Many diseases may affect the chest, and one of the most common symptoms is chest pain.
