Artatomical: The Human Heart, circa 1900

I featured this image once before in the gallery "Seven Anti-Valentine's Day Hearts," but the image is too potent not to spotlight here. What we see here is medical illustration of a human heart, notable for its ventricular wall rupture following infarction -- that's tissue death caused by a local lack of oxygen. The artist is unknown.

Artatomical is a continuing exploration of that place where anatomy and art converge, sometimes in the form of medical illustration.

About the Author: Robert Lamb spent his childhood reading books and staring into the woods — first in Newfoundland, Canada and then in rural Tennessee. There was also a long stretch in which he was terrified of alien abduction. He earned a degree in creative writing. He taught high school and then attended journalism school. He wrote for the smallest of small-town newspapers before finally becoming a full-time science writer and podcaster. He’s currently a senior writer at HowStuffWorks and has co-hosted the science podcast Stuff to Blow Your Mind since its inception in 2010. In his spare time, he enjoys traveling with his wife Bonnie, discussing dinosaurs with his son Bastian and crafting the occasional work of fiction.
