Friends, Memes, and Animal: An absolutely massive heart, submitted by our good friends over at @themedicalmentors! In fact, this heart isn't just massive - this is a heart from the largest animal on earth, The blue whale. It weighs approximately 199.6 Kilos (440 pounds)! The aorta of a blue whale's heart is so big that a human being could crawl through it. Although this heart is much bigger than the human heart, its functions through the same mechanisms, and the anatomy is very similar! science hearts bluewhales biology marinebiology medicine
