This is a fresh human heart that was donated for research. The donor was a 60 year old male with a history of hypertension, high cholesterol, coronary artery disease, and alcoholism. The heart was inflated with foam to show the anatomy as it would be while filled with blood.
We partner with [LifeSource](https://www.life-source.org/) to receive donated organs deemed not viable for transplant.
