Description: (Location & Drainage)
The parasternal lymph vessels receive lymph from the anterolateral thoracic wall and the mammary glands, as well as the upper abdominal wall above the umbilicus and the anterosuperior surface of the liver. The efferent vessels course superiorly, and usually unite with the paratracheal lymph vessels, thus forming the bronchomediastinal trunks, which drain into the right lymphatic or thoracic ducts.
