1 Pulmonary arteries carry blood low in oxygen from the right side of the heart to the lungs and often contain blue latex. 2  Pulmonary veins carry blood rich in oxygen to the left side of the heart and rarely contain any latex.he systemic circuit and the pulmonary circuit. Both circuits have arteries which lead away from the heart capillaries which connect arteries to veins and veins which carry blood toward the heart. In the systemic circuit arteries carry blood rich in oxygen from the left side of the heart toward the extremities.
But your heart does not drive blood throughout your body in a circle, but in a more of a figure-8 pattern. The heart pumps blood along two pathways in your body, the pulmonary circuit and the systemic circuit. In the pulmonary circuit, the heart pumps blood to the lungs, then back to the heart. From this pathway, blood picks up oxygen and drops off carbon dioxide in the lungs. Put simply, blood is oxygenated in the lungs. In the systemic circuit, the longer of the two, the heart pumps oxygenated blood through the rest of your body. As the blood passes through organ after organ, tissue after tissue, blood drops off oxygen, and picks up carbon dioxide.
