What is the difference between blood and hemolymph? - Blood: In a Closed circulatory system and is confined to vessels. Hemolymph (AKA interstitial fluid): In an Open circulatory system and bathes the body cells. What are the major types of blood cells? - red and white cells What adaptations allow an animal to use diffusion across its skin as the only mechanism for gas exchange? - The animal must be thin and have a large surface area.
