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.
The abdominopelvic cavity is also separated into two subdivisions, the â abdominal cavity â and â pelvic cavity â. The abdominal cavity contains the stomach, spleen, liver, intestines, and a few other organs.he walls of the ventral body cavity and outer covering of its organs contain a thin covering called the serosa (also called serous membrane). It is a double-layered membrane made up of two parts called the â parietal serosa â (lines the cavity walls) and â visceral serosa â (covers organs in the cavity).
