Oxygen is carried in the blood in two forms: (1) dissolved in plasma and RBC water (about 2% of the total) and (2) reversibly bound to hemoglobin (about 98% of the total). At physiological PO2 (40 &#60; PO2 &#60; 100 mm Hg), only a small amount of oxygen is dissolved in plasma since oxygen has such a low solubility.

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.
