Textbook Question
Chapter 23, Problem 8TYK
Which of the following is not a true statement about open and closed circulatory systems?
a. Both systems have some sort of a heart that pumps a circulatory fluid through the body.
b. A frog has an open circulatory system; other vertebrates have closed circulatory systems.
c. The blood and interstitial fluid are separate in a closed system but are indistinguishable in an open system.
d. Some of the circulation of blood in both systems results from body movements.

How does an open circulatory system differ from a closed one?
A)A closed circulatory system is completely encased in the body cavity whereas the open one is not.
B)The open circulatory system has a combination of blood vessels and large thin-walled sinuses whereas a closed circulatory system has only vessels.
C)An open circulatory system opens into the heart whereas the closed circulatory system does not.
D)An open circulatory system drains into the mantle cavity whereas a closed circulatory system drains into the hemolymph.
E)An open circulatory system opens into arteries and is drained by veins whereas in a closed one it is just the reverse.
Many objects designed by engineers have “circulatory systems” of one type or another. Describe at least three or four examples. Why do engineers sometimes include systems of flowing fluids in objects they design? We often hear it said that animal systems can teach us how to design engineered systems. If you were a biologist teaching a group of engineers about the lessons of animal circulatory systems, what principles would you emphasize?
a) List at least five things that a circulatory system does to help the body cells. Which of these is most important?
b) Name some animals with an “open circ system” ; know how it works with some vessels, heart/pumps and hemolympth blood-like fluid
c) what are the general differences between veins, capillaries and arteries?
What do we call very tiny arteries? Very tiny veins?
