The liver is the only organ that can continue to function and even regenerate after death, at least for a limited time. This unique characteristic allows portions of a deceased donor's liver to be transplanted into multiple recipients, saving several lives.
The Liver's Regenerative Capacity
The liver possesses a remarkable ability to regrow its cells and repair itself. This regenerative capacity is what makes it possible for a portion of a deceased donor's liver to be successfully transplanted. Even after the death of the donor, the liver can maintain viability for a period of time allowing for its harvesting and successful transplantation.
- Multiple recipients: A single deceased donor liver can be split and transplanted into two separate recipients.
- Post-mortem viability: Although organs have a limited time after death before they become unusable for transplant, the liver's inherent regenerative properties extend this timeframe.
Other Organs and Tissues
While other organs like the heart, lungs, kidneys, pancreas, intestines, and corneas can also be transplanted after death, their viability is significantly shorter. The timeframe is typically limited to a few hours outside the body. This underscores the liver's unique position in post-mortem organ donation.

- Other organs: Kidneys, pancreas, intestines, etc., also have limited post-mortem viability. [Source: Various articles]
The Importance of Organ Donation
The ability to transplant organs after death significantly improves the chances of survival for individuals with end-stage organ failure. The liver's unique regenerative capacity highlights its importance in this life-saving process. Organ donation is a crucial act of compassion and generosity, offering hope and a second chance at life for many.
