More Information
Fish have a closed circulatory system, meaning blood is confined within vessels and not free in the body cavity. Their system is relatively simple, consisting of a two-chambered heart.
Tips
A common mistake is to confuse open circulatory systems with closed systems. In an open system, blood freely circulates in outer cavities, which is not the case with fish.
