• \An anatomical structure that consists of the maximal set of organ parts so connected to one another that together they constitute a self-contained unit of macroscopic anatomy, distinct both morphologically and functionally from other such units. Together with other organs, an organ constitutes an organ system or a body part. An organ is divisible into organ parts but not organs (examples: femur, biceps, liver, heart, aorta, sciatic nerve, ovary).\Organ part\Digestive organ part\Lower gastrointestinal tract part (body structure)\Anal canal structure\Structure of wall of anal canal\Structure of mucous membrane of anal canal\Structure of transition zone of anal mucous membrane\Entire transition zone of anal mucous membrane
