  1. Adventitia

    Adventitia is the outermost connective tissue covering of any organ, vessel, or other structure. It is also called the tunica adventitia or the tunica externa. For example, the connective tissue that surrounds an artery is called the tunica externa because it is considered extraneous to the artery. To some degree, its role is complementary to that of the serosa, which also provides a layer of tissue surrounding an organ. In the abdomen, whether an organ is covered in adventitia or serosa depends upon whether it is peritoneal or retroperitoneal: ⁕peritoneal organs are covered in serosa ⁕retroperitoneal organs are covered in adventitia In the gastrointestinal tract, the muscularis externa is bounded in most cases by serosa. However, at the oral cavity, thoracic esophagus, ascending colon, descending colon and the rectum, the muscularis externa is instead bounded by adventitia. Generally, if it is a part of the digestive tract that is free to move, it is covered by serosa, and if it is relatively rigidly fixed, it is covered by adventitia.
