If you can handle seeing the heart of bison dissected from a teddy bear, check out this really sweet(?) video all about the anatomy of the heart.
Looks like Hank Green of Vlogbrothers fame (his brother, John Green, wrote The Fault in Our Stars) was a producer, and the YouTube channel, The Brain Scoop, is really just getting started. Friendly warnings at the beginning of each episode alert you to possible gross-out moments, so no worries…if you heed the advice. I like gross science stuff, so I found it fascinating.
Emily Graslie, the host of The Brain Scoop and the volunteer Curatorial Assistant for the Philip L. Wright Zoological Museum at The University of Montana, is funny and engaging, exploring and explaining zoological anatomy and the workings of a zoological lab.
