If you give your organs to someone else, you won't die.
The heart, lungs, liver, and kidneys are called organs. When an organ is no longer able to fulfill its function due to disease, it is replaced with an organ donated by another person, which is called an organ transplant.
The word "transplant" originally meant replanting, but is now also used for organs.
Organs may be donated from a "brain dead" person or from a living person. Brain death is a condition in which the body is alive but the brain is dead and is thought to never regain consciousness. Various organs, including the heart, lungs, and liver, are removed from a brain-dead person and transplanted.
Receiving an organ from a living person is called a "living donor transplant. A family member donates one of the two left and right kidneys, or part of a lung, liver, or pancreas. The most common type of transplant is a kidney transplant. This is because even if one of the two organs is removed, as long as the other one is working properly, the patient can live.
If a vital organ like the heart were to be taken out and given to someone else, it would, of course, not be able to survive.
