Phylum Cnidaria (e.g. jellyfish, corals) have an open circulatory system. This means that their circulatory fluid, called coelomic fluid, bathes their internal organs directly in nutrients and oxygen. There is no distinction between blood and interstitial fluid in an open circulatory system.
Cnidarians, such as jellyfish, use diffusion to transport nutrients and gases. Arthropods have an open circulatory system where blood bathes the organs directly. Fish have a closed circulatory system with a two-chambered heart, while mammals have a closed circulatory system with a four-chambered heart that efficiently circulates oxygen and nutrients to all parts of the body.
