Tigers are mammals so their circulatory system is also very similar to that of humans. The tiger's heart has 4 chambers; there are 2 different heart chambers, one being for transporting the blood and the other for receiving the blood. The ventricles are much larger than the atria and their thick, muscular walls are used to forcefully pump the blood from the heart to the body and lungs. Answered By John Thomas
