2. When did the first heart transplant take place ?
the heart is the body's most vital organ. lf it stops working, death soon follows. But many people in our time have bad hearts and suffer from heart disease. Christiaan Barnard, a South African surgeon, gave these people new hope when he performed the first human heart transplant, after at least twenty trials on dogs, in 1967. He took the heart of an accident victim shortly after death and used it to replace a sick man's heart. Since then, many successful transplants have been carried out and there are people who have lived with transplanted hearts for seven years and more. Kidneys have also been transplanted, through the success rate in liver transplants is still very low.
