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.
Arteries usually carry oxygen-rich blood. The exception is the pulmonary artery, which carries oxygen-poor blood from the right ventricle to the lungs. Arterioles are smaller arteries that carry oxygen-rich blood.he pulmonary veins, carrying blood from the lungs to the left atrium of the heart, are the only veins carrying oxygenated blood. Oxygen rich blood from the lungs is returned to the heart via the pulmonary vein.
