Left Lung

The heart has been deflected to more clearly show the major vessles associated with it. Deoxygenated blood enters the right side of the heart and leaves via the pulmonary artery (1). Upon leaving the heart the pulmonary artery divides with one branch going to the left lung and the other going to the right lung. Oxygenated blood returns to the left side of the heart in the pulmonary vein (2). After passing through the left side of the heart the oxygenated blood flows into the aorta which arches above the heart. Branchs off the aorta carry oxygenated blood to distant regions of the body.

The pulmonary artery is the only artery that contains blue latex and the pulmonary vein is the only vein that contains red latex.
