Arteries. The arteries are major blood vessels connected to your heart. 1  The pulmonary artery carries blood from the right side of the heart to the lungs to pick up a fresh supply of oxygen. 2  The aorta is the main artery that carries oxygen-rich blood from the left side of the heart to the body.eins. The veins also are major blood vessels connected to your heart. 1  The pulmonary veins carry oxygen-rich blood from the lungs to the left side of the heart so it can be pumped to the body. 2  The superior and inferior vena cavae are large veins that carry oxygen-poor blood from the body back to the heart.
Arteries carry blood low in oxygen from the right side of the heart to the lungs to be oxygenated. Blood high in oxygen enters the left side of the heart in the pulmonary vein and is pumped into the systemic circuit. The pulmonary arteries and veins are unique in the type of blood they carry.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.
