In the abdomen, there are *intraperitoneal* organs and *extraperitoneal* organs. The extraperitoneal organs are adhered to the abdominal wall; they’re “outside” the sack that contains the abdominal cavity. An example of an extraperitoneal organ is the kidneys.
As for intraperitoneal organs, it’s true that they’re just hanging in there and can shift around as you move. But what keeps them generally in place is…
**Ligaments!** And they’re all named (rip medical students).
For example, the ovaries are pinned to the abdominal wall by the infundibulopelvic ligament, the uterus is pinned to the pelvic wall by the broad and round ligaments.
