In women it is the deepest point of the peritoneal cavity, posterior to (behind) the uterus and anterior to (in front of) rectum. (The pouch on the other side of the uterus is the vesicouterine excavation.)
It is near the posterior fornix of the vagina.
It is also known by the names Douglas pouch, Douglas space, Douglas cul-de-sac.
It is named after the Scottish anatomist Dr James Douglas (1675–1742) who extensively explored this region of the female body. Three other nearby anatomical structures are also named for him - the Douglas fold, the Douglas line and the Douglas septum.
The epiploic foramen, greater sac or general cavity (red) and lesser sac, or omental bursa (blue).
