Valentine's Day... with ventricles
Given my nerd-love for all things literal, I am quite taken by this silver Anatomical Heart Locket spotted on Etsy.It opens up to reveal the four chambers of the heart, and is held shut by the trunk of the aorta. And yes, the chain is attached via the superior vena cava and the left pulmonary vein.
No detail has gone ignored... (save actual blood).
