None unless they have been genetically modified to be suitable - the organs are 'humanised'. Then, it is primarily pigs that are used.
The theory of using animal organs in human transplants is called Xenotransplantation. (Whereas using human organs in human transplants is called Allotransplantation). Xenotransplants are incredibly rare, since the outcomes are nowhere near as good as allotransplants, and the risks are far greater.
yes kill them all
the animal could have a really bad disease and could kill what thing the organ went to.
Animal to animal transplants only ever occur for research purposes, not life-extension of family pets. However when researching for human transplants, many animal transplants have to be done.
To preserve the organs before the transplant process begins.
Because, we can't clone anything at all right now.
yes
not too sure
people have transplants because their organs have problems there for they need new ones to help them survive or else they will die.
well when i cut people open i use a spoon then i just rip their organs out. (: hope that helped
Unlike human-to-human transplants, the animals are generally slaughtered specifically to provide the organ.Bovine or porcine heart valves don't usually last as long as a mechanical valve. However, there is the advantage that you don't need to take cumadin (rat poison) for the rest of you life with an animal replacement.
They already happen, so clearly social consensus is that "they should happen". Otherwise transplants would not be happening. Also, those who donate their organs are clearly in favor of organ transplants happening.
