Abdominopelvic cavity

Summary
The abdominopelvic cavity is a body cavity that consists of the abdominal cavity and the pelvic cavity. The upper portion is the abdominal cavity, and it contains the stomach, liver, pancreas, spleen, gallbladder, kidneys, small intestine, and most of the large intestine. The lower portion is the pelvic cavity, and it contains the urinary bladder, the rest of the large intestine (the lower portion), and the internal reproductive organs. There is no membrane that separates out the abdominal cavity from the pelvic cavity, so the terms abdominal pelvis and peritoneal cavity are sometimes used. There are many diseases and disorders associated with the organs of the abdominopelvic cavity. The stomach sits on the left side, which is attached to the esophagus tube. Food comes through the esophagus, goes behind all of the other organs in the thoracic cavity, then comes out through the esophagus and opens up into the stomach. The stomach is more of an acidic environment, and begins the major processes of digestion. The food particles must be broken down before entering the small intestine. The small intestine is about 20 feet and goes behind the large intestine, and then makes a mass of curly tube. The small intestine is divided into three parts: the duodenum, jejunum, and the ileum. The duodenum receives particles from different organs, like the pancreas. The pancreas produces the hormone insulin, which helps regulate blood sugar. The second part is the jejunum, which is located in the middle of the small intestine. The final part of the small intestine is the ilium. It is connected to the large intestine. The ileum is connected to the ileum cecum valve, which is the beginning of the large intestine. The large intestine, also known as the large bowel, is the last part of the gastrointestinal (GI) tract and of the digestive system. The liver lies in the right hypochondrium area and the greater portion of the epigastric areas of the abdominal cavity under the diaphragm within the rib cage. It is a processing and detoxifying organ.
