Circulatory System
Lions have a closed circulatory system. This means the blood is closed at all times within the lion. Blood flows through vessels only. Their heart has four chambers, just like humans. Circulatory system is the same as other felines, but it is much larger. The major tissues of the lions circulatory system are the muscle, the spleen, the heart, the lungs, and the mouth. The major organs of the circulatory system are the veins.
