Peritoneal Cavity

The peritoneal cavity (cavum peritonei, pna; cavum peritonei, bna, jna; synonym peritoneal cavity) is the largest cavity of the body; it can be considered as a gap between the outer (parietal) and inner (visceral) parts of the peritoneum.

The peritoneum lines the inner surface of the abdominal wall and duplicates the flat organs of the abdominal cavity (liver, stomach, spleen, etc.), forming a double peritoneal cover around them. The peritoneal cavity is divided into two parts: the upper (the cavity of the greater omentum) and the lower (the pelvic cavity).

The abdominal cavity contains the organs of the digestive, urinary and reproductive systems, as well as large vessels and nerves. The main functions of the peritoneal cavity are to protect internal organs, prevent adhesions and ensure their mobility by contracting the smooth muscles of the peritoneum.

During pregnancy, it plays a significant role in the development of the fetus, protecting it from mechanical injuries and preventing the displacement of internal organs, because weight is constantly increasing. To increase the elasticity of the tissue during pregnancy, the moisture content increases tenfold. As many people age
