移植是將組織或器官從一個個體轉移到另一個個體，或在一個個體內從一個部位轉移到另一個部位的過程。移植組織或器官替換受損或缺失的組織，并在受體中起作用。

Transplantation is the procedure of transferring a tissue or organ from one individual to another or from one site to another within a single individual. The transplanted tissue or organ replaces damaged or absent tissue, and is functional in the recipient.
