Organ transplant involves surgically removing an organ or tissue from one person (donor) and placing it in another person (recipient). Common transplanted organs include the heart, kidneys, liver, lungs, and pancreas. Countries have systems to manage organ allocation and reduce transplant rejection. The Philippines first performed transplants in 1990 and now has transplant programs, though demand still exceeds available organs. Ethical debates surround issues like living donation, organ markets, and accusations of forced donation from non-consenting groups.
