where does the thoracic duct receives 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]
Vein Veins are less muscular than arteries and are often closer to the skin. There are valves in most veins to prevent backflow.
Limit of a function (the Dirichlet function) has no limit at any x-coordinate.
Tonsil Tonsils are collections of lymphoid tissue[1] facing into the aerodigestive tract. The set of lymphatic tissue known as Waldeyer's tonsillar ring includes the adenoid tonsil, two tubal tonsils, two palatine tonsils, and the lingual tonsil.
