What part of speech is transplantation almost exclusively used as?

Answer

Noun referring to the abstract process or act

Transplantation is consistently designated as a noun whose primary function is to name the entire act, procedure, or process involved in the transfer of material. Unlike the word 'transplant,' which can function as both a verb (to move something) and a noun (the item moved), 'transplantation' specifically denotes the comprehensive procedure itself. This includes all preparatory steps, such as harvesting, preservation, and implantation, making it the formally preferred term when discussing the overall clinical intervention, such as kidney transplantation or bone marrow transplantation, rather than focusing solely on the resulting physical graft.
