Why is it possible to perform a liver transplant using just a small part of a donor’s liver, but for other organs (kidney, heart, etc) the donor would have to donate the whole organ?

Basically most organs are made up of permanent tissues whose cells can not regenerate at all, whereas the liver’s tissue is known as stable tissue which does have the ability to replicate but only in response to injury i.e cutting a part for a transplant. Note that stable tissues have minimal ability to replicate but the liver is the exception and has a great ability to regenerate about half of its full form. Why is the liver the exception? That I do not know.
