I was wondering, can a six foot tall person donate, let's say, a kidney to a four foot tall person? Do discrepancies in organ size limit what can be excepted by a patient needing a transplant? Also, and I may be way off on this, but isn't there a substantial amount of Hindu and Buddhist organ donors? And, hypothetically speaking, don't people of those faiths tend to be smaller in stature? Is there a certain amount of possible transplantable material that is, um, too small for people waiting for transplants? I know blood type is what you normally need for compatibility, but I was wondering what the other factors are as well. Any help?
