b. They are responsible for the movement of the body.
c. They break down food into energy and eliminate waste.
d. They send chemical signals throughout the body via hormones.
15. The circulatory and respiratory systems work together to provide cells with oxygen and nutrients and remove wastes such as carbon dioxide. When the body needs more oxygen, how does the circulatory system respond?
a. The blood vessels in the arms and legs constrict to conserve oxygen.
b. Blood moves more slowly through the organs to carry away more wastes.
