Can anyone Tell Me what’s a Transplant is

Answer 1

Birbwu, she/he asked what a transplant was, not a heart transplant..

Answer 2

Answer:

A heart transplant is a surgery in which doctors remove a person's sick heart and replace it with a healthy donor heart. ... They choose to donate the organs because they want to help someone else who is sick.

Here's another example:

Mayo Clinic is the largest integrated transplant provider in the United States. Mayo Clinic has pre-eminent adult and pediatric transplant programs, offering heart, liver, kidney, pancreas, lung, hand, face, and blood and bone marrow transplant services. 

Have a nice day!
