This is a perfusion fixed human heart that was donated for research. The donor was a 56 year old woman with a history of smoking. This model shows a longer portion of the descending aorta down the back of the heart. The aorta descends from the heart all the way down to the pelvis, where it branches in two. This heart uses reference number: 0506
We partner with [LifeSource](https://www.life-source.org/) to receive donated organs deemed not viable for transplant.
