Proceeding from before backwards, we first find the Pulmonary artery* where it divides into its two great branches, one passing un¬ der the arch behind the ascending portion of the Aorta, to get to the right side of the thorax, and the other passing to the left before the descending Aorta, towards the lung of the same side.
