The body of the uterus is surrounded by peritoneum, hence it lies intraperitoneal. The kidneys, and the large vessels - the aorta and the inferior vena cava- lie posterior to the peritoneal cavity: retroperitoneal.

Correspondingly, are ovaries in the retroperitoneal space?

The retroperitoneal (or lumbar) lymph nodes are the regional lymph nodes for the organs of the retroperitoneal space, and also for the testes, ovaries, fallopian tubes, and uterus (which are embryologically derived from the retroperitoneum).

What are the retroperitoneal organs?

Is the prostate retroperitoneal?

What is the peritoneum and what is its function?

Are Paracolic gutters retroperitoneal?

The main paracolic gutter lies lateral to the colon on each side. It is continuous with the peritoneum as it descends into the pelvis over the pelvic brim.

What is the difference between peritoneum and omentum?
