Show me a diagram of the human heart? Here are a bunch! - Interactive Biology, with Leslie Samuel
The human heart is a magnificent organ. The adult heart pumps about 1,500 to 2,000 gallons per day. I'm not going to get into a lot of details about the heart in the post right now because I'm gonna get more into it later. I just wanted to post a few 3D pictures of the human heart, because I think they are amazing. They were done by Patrick J. Lynch, medical illustrator for Yale University.
