Answer 1

Answer:

This is the answer

Explanation:

In an open circulatory system, the blood is not enclosed in the blood vessels, but is pumped into a cavity called a hemocoel. ... As the heart beats and the animal moves, the hemolymph circulates around the organs within the body cavity, reentering the heart through openings called ostia (singular: ostium).
