Do fish have an open or closed circulatory system? What does this mean?​
dedylja [7]

Answer:

They have a closed circulatory system.

Explanation:

In an open circulatory system, blood vessels transport all fluids into a cavity. When the animal moves, the blood inside the cavity moves freely around the body in all directions.

Closed circulatory systems are different to open circulatory systems because blood never leaves the blood vessels. Instead, it is transferred from one blood vessel to another continuously without entering a cavity.
