The descending colon is primarily considered retroperitoneal, meaning it is located behind the peritoneum, the membrane lining the abdominal cavity. Unlike the intraperitoneal organs, which are surrounded by peritoneum and have a greater range of mobility, the descending colon is fixed in place and does not have a mesentery. This position is part of its anatomical relationship within the abdominal cavity.
