Answer:
The correct answer is E. Vertebrates have a closed circulatory system.
Explanation:
The main mission of the circulatory system is to deliver oxygen and nutrients to all body cells.
In the closed circulatory system, blood travels inside a network of blood vessels, without leaving them. The material transported by the blood reaches the tissues through diffusion. It is characteristic of all vertebrates, including humans.
