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.
The oxygen-poor blood from the vena cavae flows into your heart's right atrium and then to the right ventricle. From the right ventricle, the blood is pumped through the pulmonary (PULL-mun-ary) arteries (shown in blue in the center of figure B) to your lungs.he blood enters the left atrium and is pumped into the left ventricle. From the left ventricle, the oxygen-rich blood is pumped to the rest of your body through the aorta. The aorta is the main artery that carries oxygen-rich blood to your body. Like all of your organs, your heart needs oxygen-rich blood.
