The vena cava, pulmonary artery, pulmonary vein, and aorta are key blood vessels connected to the heart, responsible for circulating blood between the heart, lungs, and body.
Blood vessels associated with the heart include the vena cava (returning deoxygenated blood to the right atrium), pulmonary artery (carrying deoxygenated blood from the right ventricle to the lungs), pulmonary vein (returning oxygenated blood from the lungs to the left atrium), and aorta (carrying oxygenated blood from the left ventricle to the body).
