Organ donors are individuals who choose to give their organs or tissues to help others in need of transplants. This can include vital organs like the heart, kidneys, and liver, as well as tissues such as corneas and skin. Organ donation can save lives and improve the quality of life for patients suffering from organ failure or severe injuries. In many countries, people can register as organ donors when they obtain or renew their driver's license. Families are often consulted about the decision, and consent is crucial. Organizations like the United Network for Organ Sharing (UNOS) manage the allocation of donated organs to ensure they go to those who need them most.
