The blue whale heart is the largest heart in the animal kingdom, weighing up to 900 kilograms (2,000 pounds) and measuring about the size of a Mini Cooper. It is located in the animal’s chest, just behind the lungs. The heart has four chambers, like the human heart, and consists of two atria and two ventricles. 

The atria receive blood from the body, and the ventricles pump blood to the lungs and the rest of the body. The blue whale’s heart beats about 10 times per minute, pumping about 220 liters (58 gallons) of blood with each beat.

The aorta, the main artery that carries blood away from the heart, is about 9 inches (23 centimeters) wide. The heart valves are so large that a human could swim through them. The heart sounds can be heard up to 3 kilometers (2 miles) away.
