Walking and Injuries. Any pain in the chest while walking, no matter what its cause, can be troubling -- especially if you've reached middle age, when the risk of heart disease rises. Such pain may have nothing to do with your heart, however.
The stomach, liver, spleen, gallbladder, and most of the small and large intestines are in the abdominal cavity. Many of the organs of the abdominopelvic cavity are covered by the visceral peritoneum, while the wall of the abdominal cavity is lined with the parietal peritoneum. Peritoneal fluid fills the cavity between the visceral and parietal peritoneum.
abdominopelvic cavity is divided into the abdominal cavity and pelvic cavity. The abdominal cavity is between the diaphragm and the pelvis. It is lined with a membrane and contains the stomach, lower part of the esophagus, small and large intestines (except sigmoid and rectum), spleen, liver, gallbladder, pancreas, adrenal glands, kidneys and ureters. The pelvic cavity contains the bladder, some reproductive organs and the rectum.
