Circulatory systems are classified as open or closed. In an open circulatory system, the heart pumps a fluid through arteries that empty into a large space, the hemocoel. The fluid bathes the organs in the hemocoel, and returns through veins to the heart.
The circulatory and respiratory system interactions form the basis for supporting life in higher animals. The heart, arteries, veins, lungs and alveoli have to work together to supply the body with oxygen and get rid of carbon dioxide, the human respiratory system's form of waste.
