Because the tissues of the donated organ have to match those of the patient. Not all tissue types are compatible with each other, and if they are not, then the body just rejects the donated organ and cannot use it.
Modern pathology testing can go some way towards assessing beforehand if an organ is compatible with the recipient, but there are still occasions when donated organs are rejected for reasons that nobody understands. However, this doesn't necessarily mean that the patient faces death- often the organ will work a bit, not as it should do but for long enough for another donor organ to be found that WILL work.

Organ transplant that have been successfully since1990?
Most (common) transplants have been considered 'successful' since 1990. Ciclosporin (the first good immunosuppressant) was approved for use in 1983. From then on, success rates all improved dramatically.
What do euthanasia organ transplants and gentic engineering have in common?
They all make the general public feel uncomfortable, yet opinionated?
Can HIV be transmitted without semen?
Yes. Blood, sexual fluids, and organ transplants all transmit HIV.
Why are some transplants successful and some unsuccessful?
Some transplants simply do not work. Until the transplanted organ is in place in the patient's body and connected, it is not possible to know if it is going to 'function' or not. At this stage, it is obviously not possible to go back. The length of time that the organ has been out of the body before transplantation adversely affects how the graft (organ) functions. Sometimes it affects grafts in very odd ways; the graft can be transplanted in appearing healthy, but does not work. If the patient is retransplanted, or if the organ is removed during an autopsy within a few days, the graft can by covered in small tumors, or hard patches, all in the space of days. (All organs are thoroughly checked for abnormalities before transplantation). So far it's not possible to tell if a transplant is going to be "successful" or not; it's still guesswork. Some transplants fail due to organ rejection (whether acute or chronic), some fail due to non-compliance with drug regimes, some fail for unknown reasons.
Why were there more organ transplants then donors?
The discrepancy between organ transplants and available donors is primarily due to a higher demand for organs than the supply. Factors contributing to this include an increasing prevalence of chronic diseases, such as diabetes and kidney failure, which heighten the need for transplants. Additionally, not all potential donors can be used due to medical or logistical reasons, leading to a significant gap between those in need of transplants and the number of viable organs available. Efforts to raise awareness and improve donor registration are ongoing to help bridge this gap.
How have discoveries about organ and how the body works helped scientists improve organ transplants?
discoveries about organs and how the body works have helped scientists because if we didnt know how the body works and how many bones and muscles and things like that we all have, then scientists wouldnt know wheather or not to give us an organ translpant
What if your insurance doesn't cover transplants?
most health insurance plans do cover transplants...but not all.
Should the less eligibility principle apply to organ transplants for inmates?
The less eligibility principle, which suggests that prisoners should not receive benefits that exceed those available to the general population, raises ethical concerns in the context of organ transplants. Applying this principle could lead to inequities in healthcare access for inmates, potentially denying them necessary medical treatment based solely on their incarceration status. This approach may undermine the fundamental principles of medical ethics, such as justice and equity, suggesting that all individuals, regardless of their legal status, deserve fair access to life-saving interventions. Therefore, while the principle addresses resource allocation, it may be more just to ensure that all individuals, including inmates, have equitable access to organ transplants.

Why can limbs be reattached?
Most can't for rejection reasons, but they can do small things like fingers. Drugs are getting better all the time though, there have been a couple successful face transplants which was unheard of before.
Which one of your organs do not need oxygen?
ALL of the the organs in the human body need an oxygen supply. This even includes the organs responsible for delivering oxygen to the rest of the body: the heart and lungs. Every organ requires oxygen. All that can be said in this case is that some organs use/need more oxygen than others. For instance, the brain needs/uses more oxygen than the spleen.
