Do birds have open or closed circulatory systems?

Birds have closed circulatory systems, where blood flows within vessels and does not come in direct contact with the surrounding tissues. This system allows for efficient circulation and delivery of oxygen and nutrients throughout the bird's body.


How do insects move and fly actively despite the type of circulatory system they have?

Even if insects have an open circulatory system, which is usually characterized by slow animals with low metabolic rates, their circulatory system does not participate in supplication of oxygen to the tissues and in the gas exchange process. That is handled by the independent tracheal system, the spiracles, which allows direct contact of cells with the air. With this, the oxygen demand can be supplied even with an open circulatory system.source: http://www.biology-questions-and-answers.com/the-circulatory-system.html

Tigers are mammals and so their circulatory system is very similar to that of humans.


What is a hemocoel?

A hemocoel is a body cavity in invertebrate animals that contains circulating body fluids, such as blood. It functions like a circulatory system, transporting nutrients and waste products throughout the organism's body.


How would a fish's behavior change if they had an open circulatory system?

Well I'm not sure but the fish would probably be less active because the circulation wouldn't be as good in an open circulatory system so it wouldn't be able to retrieve as much oxygen for its energy level and it would need to slow down.
