Subphrenic spaceThe area of the peritoneal cavity that lies directly below the diaphragm.
Peritoneal cavityA potential space between the parietal and visceral peritoneum, housing many abdominal organs.
Supracolic compartmentThe part of the peritoneal cavity above the transverse colon, containing the stomach and liver.
Infracolic compartmentThe part of the peritoneal cavity below the transverse colon, extending into the pelvis.
PelvisThe lower part of the torso, forming the basin of the spine and housing parts of the digestive and urogenital systems.
StomachA digestive organ that processes food by secreting acid and enzymes.
Transverse colonThe middle section of the large intestine, passing from right to left across the abdomen.
Third part of the duodenumThe horizontal section of the duodenum, the first part of the small intestine.
Superior mesenteric arteryA major artery that supplies blood to the small intestine and parts of the large intestine.
Lesser sacThe division of the peritoneal cavity behind the stomach.
Greater omentumA large fatty structure attached to the stomach, draping over the intestines, with immunological functions.
DiaphragmA large, dome-shaped muscle that separates the thoracic cavity from the abdominal cavity and plays a major role in breathing.
LiverA vital organ involved in metabolism, detoxification, protein synthesis, and other essential bodily functions.
AortaThe largest artery in the body, originating from the left ventricle of the heart and extending down to the abdomen where it branches off.
Visceral peritoneumThe inner layer of the peritoneum that surrounds the abdominal organs.
Parietal peritoneumThe outer layer of the peritoneum that lines the abdominal and pelvic cavities.
MesenteryA fold of the peritoneal cavity that attaches the stomach, small intestine, pancreas, spleen, and other organs to the posterior wall of the abdomen.
