Blue Whale Heart
The largest heart in the animal kingdom/Everyday Objects
The heart of a blue whale is roughly the size of a golf cart and weighs about as much as three adult humans. It beats only 8 to 10 times per minute at the surface and can slow to as few as 2 beats per minute during a deep dive. Each beat pumps about 80 liters of blood through a body that can exceed 30 meters in length. The aorta is large enough for a small child to crawl through, which is a fact that comes up at every marine biology lecture.
