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.
Once you have opened the body cavity, you will need to rinse it in the sink. 1. Locate the diaphragm, which is a layer of muscle that separates the thoracic from the abdominal cavity. 2. The heart is centrally located in the thoracic cavity.The two dark colored chambers at the top are the atria (single: atrium), and the bottom chambers are the ventricles.. The coelom is the body cavity within which the viscera (internal organs) are located. The cavity is covered by a membrane called the peritoneum, which is very thin and web-like, you may need to use forceps to remove some of this membrane to see the organs clearly.
