Organ Donation and Transplantation
1 Organ donation(捐献) and transplantation(移植) refers to the process by which organs or tissues from one person are put into another person's body.
2 The number of people needing a transplant continues to rise faster than the number of donors. About 3,700 transplant candidates are医学全.在线www.lindalemus.com added to the national waiting list each month. Each day, about 77 people receive organ transplants. However, about 18 people die each day waiting for transplants that can't take place because of the shortage of donated organs.
3 There are no age limits on who can be an organ donor. Newborns as well as senior citizens have been organ donors. If you are younger than 18, you must have a parent's or guardian's consent (同意). If you are 18 years or older, you can show you want to be an organ and tissue donor by signing a donor card.
