Both single and double circulatory systems are closed, involve capillaries, and use a pumping organ. Differences include blood passing through the heart once in single vs. twice in double circulation, the number of heart chambers, the direct flow of oxygenated blood from respiratory organs to capillaries in single circulation, and lower blood pressure in single systems.
