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.
The right atrium and the right ventricle pump blood into the lungs via the pulmonary artery. The blood picks up oxygen in the lungs and returns to the heart through the left atrium and left ventricle. The left atrium pumps blood through other parts of the heart and the rest of the body. The oxygenated blood circulates through the body. Deoxygenated blood from the body goes back to the right atrium where the process begins again. The aorta and the coronary arteries play an important role in providing oxygenated blood to the rest of the heart. The coronary arteries help move oxygenated blood from the aorta to the heart. The aorta provides oxygenated blood from the left atrium and left ventricle to the rest of the body.
