Greater sac

The greater sac or general cavity (red) and lesser sac, or omental bursa (blue).

In human anatomy, the greater sac, also known as the general cavity (of the abdomen), is the cavity in the abdomen that is inside the peritoneum but outside of the lesser sac.

It is connected with the lesser sac via the epiploic foramen, also known as the Foramen of Winslow.
