Classify the following characteristics as either describing an open circulatory system or a closed circulatory system. Open Circulatory System Closed Circulatory System Blood is always contained within blood Gas exchange occurs in capillary beds vessels Typical of crayfish, insects, and clams Allows for lower hemolymph pressure and velocity Contains fluid called hemolymph Hemolymph is transported to sinuses, where the organs are directly bathed Coeloms are large and well-developed Valves are employed to prevent blood from flowing in the wrong direction...

NAME SID__ 31. Which of the following is a correct statement when comparing Open Circulatory Systems and Closed Circulatory Systems? a. Open Circulatory Systems generally require MORE energy to operate, since it is less efficient to circulate the entire amount of interstitial fluid in the body cavity. 8. Arthropods and Insects generally use a Closed Circulatory System, while vertebrates generally use an Open Circulatory System Both systems utilize some form of the following three components: (1) circulatory fluid, (2) vessels...
