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’ve been trying to find a bunch of diagrams and pictures for my blog and I found some great stuff. I just wanted to post a few pictures of the human heart, because I think they are amazing.

There are some regular pictures and some 3d pictures of the human heart. If you click on the images, you will see them in Full Size. Feel free to download and use them as necessary. However, if you do that, make sure to retain the copyright info on those containing the copyright info.

    Samuel, I (56 years old) am studying to become an EKG technician. I have a great book, “Understanding EKG’s – A practical Approach” by Brenda Beasley. As detailed as it was, I would of never gotten through this course without your web site. You put everything into perspective with your techniques vs. just reading it. I have recommended your site to other students and will return as I continue my medical journey. Thank you!

    I have seen your video ( on different EKG subjects ) & it was simple, Clear , most of all, very easy understand & learn. I wish you were our school teacher!

    I wish you were my teacher back in the day – maybe I wouldn’t have done so bad in science! (P.S. I am 50 years old and came upon your site when looking for a diagram of the heart just for my own knowledge.)
