我们人体跟机器一样,也有很多“零件”,如心脏、肝脏、肾等器官,如果某个器官严重损坏了,人体的生理机能就不能正常运转。这时,医生就像给机器换零件一样,除掉病人身体中有病的器官,换上一个结构、功能都正常的健康器官,这就是器官移植。目前,全世界已有30多万人依靠移植的器官像正常人一样生活和工作。 Like human beings, we have a lot of “parts”, such as the heart, liver, kidney and other organs. If an organ is severely damaged, the body's physiology can not function properly. At this time, the doctor, like giving the machine a replacement part, removes the diseased organ in the patient's body and replaces it with a healthy organ of normal structure and function. This is the organ transplant. Currently, more than 300,000 people around the world rely on transplanted organs to live and work like normal people.
