Capillaries connect the arteries to veins. The arteries deliver the oxygen-rich blood to the capillaries, where the actual exchange of oxygen and carbon dioxide occurs. The capillaries then deliver the waste-rich blood to the veins for transport back to the lungs and heart. Veins carry the blood back to the heart.
In the systemic (body) circuit, arteries carry oxygenated blood and veins carry deoxygenated blood. In the pulmonary (lungs) circuit, the arteries carry deoxygenated blood while the veins carry oxygenated blood. You are correct in your description of what carries oxygenated blood in the pulmonary circuit.
