Lecture 1/19/12 Chapter 42 Circulation Big Questions / Learning Objectives 1. Describe the interrelationship between body size and the need for a circulatory system. 2. Compare and contrast open and closed circulatory systems. 3. Compare and contrast single and double circulation and relate each to anatomy and physiological needs. 4. Describe the adaptive nature of differences among the double circulatory systems of amphibians, non-avian reptiles, and mammals. 5. Diagram the variation in blood velocity and pressure along the vertebrate circulatory system and define the causes. 6. Explain the adaptive nature of pump fusion in the evolution of double circulation. 7. Describe the cardiac cycle, distinguishing between systole and diastole. 8. Describe how the flow of electrical signals from the pacemaker coordinates heart function. 9. Characterize the heart valves by location, structure, and function. 10. Relate the structure of capillaries, arteries, and veins to their function.
