Systemic circulation carries oxygenated blood from the left ventricle, through the arteries, to the capillaries in the tissues of the body. From the tissue capillaries, the deoxygenated blood returns through a system of veins to the right atrium of the heart.ystemic circulation carries oxygenated blood from the left ventricle, through the arteries, to the capillaries in the tissues of the body. From the tissue capillaries, the deoxygenated blood returns through a system of veins to the right atrium of 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.
