In females, the most inferior portion of the peritoneal cavity is which pouch?

• A. Rectouterine Pouch
• B. Rectovesical Pouch
• C. Pouch of Morison
• D. Heporenal recess

Answer: (A)

In the female, the deepest recess of the peritoneal cavity is the rectouterine pouch, also called the pouch of Douglas. This space lies between the posterior surface of the uterus and the anterior surface of the rectum, making it the lowest peritoneal pocket where fluid tends to accumulate. It’s the pelvic counterpart to the rectovesical pouch in males, which sits between the rectum and bladder.

Other peritoneal recesses mentioned have different locations: the hepatorenal recess (pouch of Morison) is in the upper abdomen, between the liver and right kidney, and is the most dependent part of the peritoneal cavity only in certain supine positions, not in the pelvis.
