The Giant Heart

Stroll through the iconic Giant Heart like people have done for over fifty years. Hear the sounds of an actual human heartbeat as you go through the chambers. See live heart and eye dissections daily in our state-of-the-art demonstration space. How much blood is in your body? What does the inside of a human body look like? Watch video of a real beating heart undergo surgery, view hand-painted red blood cells lining the walls, and walk across the world’s largest map of Philadelphia as you gain insight into local public health issues.
