Thorax Veins

Human anatomy > Circulatory System > Thorax Veins

It is the superior vena cava that accepts blood from brachiocephalic veins, and the azygos system occurring in the veins. This so called azygos vein running with respect to the thorax, specifically in its superior wall and also in the abdomen. It will also pass through the vertebral column’s right side and then through the mediastinum it rises.

Attached with the azygos system is the ascending lumbar veins. They function as a drainage for the sacral and lumbar areas. The intercostal muscles rely and work hand in hand with the intercostal veins for drainage. The hemiazygos veins, on the other hand is responsible for the formation of major tubular network drainage to the vertebral column’s left side.
