Briefly describe the differences among animal circulatory systems. What is an open system versus a closed? What are the anatomical differences among vertebrate hearts?
A large grasshopper and a small mouse may be similar in size. However, the total length of blood vessels is much greater in the mouse, and the mouse’s heart pumps at much higher pressure than the grasshopper’s hearts. Which statement is most useful for explaining these observations?
Three circulatory systems of vertebrates are represented in the following diagram. Identify
to which group of animals each circulatory system belongs and mention the reasons for
considering them as such.
