What is the term for the joining of parts, whether natural or surgical?

The term "anastomosis" refers specifically to the joining or connection of parts, particularly in a biological or medical context. This can occur either naturally, such as the connection of blood vessels, or surgically, where surgeons may create new pathways by connecting structures like arteries or intestines. The significance of anastomosis lies in its role in ensuring that blood flow or organ function remains intact, especially after surgeries or in conditions where natural pathways may be compromised.

Other terms, while related, do not convey the same precise meaning as anastomosis. "Adhesion" typically refers to the abnormal sticking together of tissues, which can occur after surgery or due to inflammation. "Fusion" generally refers to the process of joining two or more entities together but is often used in a broader sense, applicable to both biological and non-biological contexts. "Amalgamation" is mainly used in processes involving the combination of different elements or substances, particularly with metals and does not specifically address the biological joining aspect that anastomosis does.
