The easiest organ to live without is your gallbladder.
The gallbladder is a small organ which stores bile and helps digest fats, although the liver is able to perform the function alone when the gallbladder is removed.
You can also live without one of the kidneys, portions of the liver and with one lung.
You can also live without reproductive organs.
The liver is also capable of regeneration, which means that it can grow back parts of itself if it's damaged or removed.
The organ that has the longest waiting list is the kidney as there are over 90,000 people waiting for a kidney transplant and the average wait time for kidney transplants is between 3 years to 5 years.
The high wait time for kidney transplants is due to high demand for kidneys and also a shortage of kidney donors.
There are over 24,000 kidney transplants that are performed globally annually due to a high prevalence of kidney disease and the relatively successful outcomes of kidney transplantation.
Kidneys can also be transplanted from living kidney donors, and is another factor that contributes to the high transplantation rates of kidneys.
The hardest transplant to recover from is a lung transplant, due to the complexity and susceptibility of infection and rejection of the lung transplant.
And other transplants that are also hard to recover from are combined heart and lung or lung and liver kidney transplants.
Lung transplants are the most difficult transplants to recover from because the lungs are highly susceptible to infection as well as damage during the retrieval and transplant process.
The rarest organ transplant is a triple organ transplant.
A triple organ transplant is a transplant that involves the heart, liver and kidney.
Triple organ transplants are very rare, and less than 80 triple organ transplants have been attempted in the United States, within the last last couple of decades.
Another rare transplant is a syngeneic transplant, which is where a stem cell donor is an identical twin.
The most sought after organ transplant is a kidney transplant.
In the United States, a significant portion of the waiting list for transplants are people waiting for kidney transplants.
The demand for kidney transplants far exceeds the available kidneys for transplant.
The organ that cannot be transplanted is the brain.
The brain is the organ that cannot be transplanted because the brain is a complex organ and delicate organ that is responsible for controlling of all the bodily functions.
The brain is also very and extremely difficult to reconnect and to disconnect to another body without causing severe damage.
The lungs are often the most difficult organ to transplant as a result of several factors which include a higher risk of chronic rejection as well as infection and difficulty in preserving the donor lungs for transplant.
Some factors that make lung transplants pretty challenging to transplant include.
High Risk of Chronic Rejection.
A significant percentage of lung transplant recipients develop chronic lung allograft dysfunction also known as CLAD within 5 years, which is a form of chronic rejection.
Infection Vulnerability.
The lungs are susceptible to infections, especially in the late stages of a lung donor's life, which can also complicate the transplant process.
Preserving donor lungs for transplant can also be difficult as they are fragile and also susceptible to damage.
Lung transplant recipients also have a lower long term survival rate when compared to other organ transplants, partly due to CLAD.
