Organs that can be donated when alive:
- Kidney: One of the most common organs that can be donated when alive is the kidney. A person can live a healthy life with just one functioning kidney, so they can choose to donate one of their kidneys to someone in need.
- Liver: A portion of the liver can also be donated when alive. The liver has the ability to regenerate, so both the donor and the recipient's livers can grow back to their original size after donation.
- Lung: While less common, a portion of a lung can also be donated by a living donor. This is usually done in cases where the recipient is a family member or a close friend of the donor.

Organs that can be donated after death:
- Heart: The heart is a vital organ that can be donated after death. It can save the life of someone in need of a heart transplant.
- Lungs: Both lungs can be donated after death to save the lives of individuals with severe lung conditions.
- Liver: The entire liver can be donated after death, providing a new lease on life for someone with liver failure.
- Kidneys: Both kidneys can be donated after death, enabling two individuals to receive a life-saving kidney transplant.
- Pancreas: The pancreas can also be donated after death to help individuals with diabetes or pancreatitis.
- Intestines: In some cases, the intestines can be donated after death to individuals with intestinal failure.
These are some of the common organs that can be donated either when alive or after death to save lives and improve the quality of life for those in need of organ transplants.
