Arteries The arteries are elastic, muscular tubes that carry blood away from the heart, into the capillaries.The walls of the arteries are thicker than the other blood vessels due to higher blood pressure being present in arteries.Note that arteries don't always carry oxygenated blood, as is the case with the pulmonary artery. Veins The veins carry blood from capillaries back to the heart.he walls of the arteries are thicker than the other blood vessels due to higher blood pressure being present in arteries.
