Like a human, heart pumps blood through the veins to their destination ( i.e organs, brain... anything really ), arteries bring the bad blood back and swap the Co2 for oxygen in the lungs.
A lion's body systems include the digestive system for breaking down food, the circulatory system for transporting nutrients and oxygen, the respiratory system for breathing, the nervous system for coordination and control, and the muscular system for movement.
Their circulartion system is very similar to humans (closed circulatory system)
Animals that breathe using lungs have a pulmonary circulatory system. In this system, the lungs are dependent on the flow of blood from the systemic circulatory system, which works in tandem with the pulmonary system to provide blood flow to these vital organs.
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
no, a university proffessor would say that a rat is not included in the animals that have circulatory systems at all and they sometimes go 69 with the same sex rats
They have a heart

Ask God .....!!or test it.... if you wish too.
closed circulatory system (double circulatory system)
They're both the circulatory system.
Amphibians have closed circulatory system Closed
The circulatory system
open circulatory systemclosed circulatory system.
The cadiovascular system, sometimes called the circulatory system when it includes the lymphatic system.
Well,circulatory system is made up of BLOOD and heart.
i believe it is the circulatory and the cardio-vascular systems cardiovascular or circulatory
closed circulatory system.
