What is an anastomosis?

An anastomosis refers to a connection between two vessels, such as blood vessels or tubular structures. This connection allows for the flow of blood or other fluids between them, creating an alternative pathway. Anastomoses are essential in various biological systems, as they can help to maintain circulation despite blockages or other issues in one of the vessels. This phenomenon is commonly observed in the context of vascular surgery, where surgeons create anastomoses to bypass obstructed blood flow or restore proper circulation.

The other choices pertain to different medical concepts. A type of joint involves the structural connections between bones, which allows for movement. A surgical incision relates to a cut made during surgery to access tissues or organs, and inflammation is a response of the body to injury or infection, characterized by redness, heat, swelling, and pain. These definitions highlight the distinct nature of an anastomosis compared to the other terms.
