Arteries form part of the circulatory system. They carry blood that is oxygenated after it has been pumped from the heart. Arteries also aid the heart in pumping blood. Arteries carry oxygenated blood away from the heart to the tissues, except for pulmonary arteries, which carry blood to the lungs for oxygenation.
Because internal organs are called viscera, the portion of the serous membrane that attached to an organ is called the visceral layer. The lungs are attached to the heart. The heart carries deoxygenated blood through the pulmonary artery to be converted to oxygenated blood in the lungs. The oxygenated b â¦ lood returns to the heart through the pulmonary veins. + 1 other found this useful.
