Textbook Question
Chapter 40, Problem 4RQ
Why are open circulatory systems advantageous to some animals?
- They use less
metabolic energy - They help the animal move faster
- They do not need a heart
- They help large insects develop.

What is a characteristic of the circulatory systems of arthropods and mollusks that distinguishes them from
the circulatory system of echinoderms?
They have lungs.
They have muscular pumps to circulate the extracellular fluid.
They are closed circulatory systems.
They have extracellular fluid to transport substances to and from internal organs.
They have cilia to circulate the extracellular fluid.
Which circulatory system do you think is most efficient at delivering oxygen rich blood
to the tissues of an animal?
O Gastrovascular system seen in most Cnidarians
O Closed circulatory system seen in vertebrates
O Open circulatory system seen in many arthropods
In what 2 ways is an insect's circulatory system different from a vertebrate's circulatory system? (choose 2 answers)
Question 14 options:
The insect has closed circulatory system.
Insects have a tracheal system that delivers oxygen to it's cells directly so it is not associated with the circulatory system.
Insects have a tracheal system that delivers oxygen to it's circulatory system.
The insect has an open circulatory system instead of one that is closed (as in vertebrates). This means that the circulatory fluid of vertebrates moves much faster than that of insects.
