What is the abdominal cavity?

In anatomy, there are three cavities containing organs in the human fuselage: the thoracic cavity in the thoracic basket, the abdominal cavity and the pelvic cavity. The latter two cavities are often considered a unit and are therefore referred to as the abdominal cavity. It is located under the membrane muscle, which forms the floor of the rib cage and extends into the pelvis. In the Abdominopelvic cavity, the main organs of digestion - stomach and intestines - and reproductive organs are the main organs. The additional organs of digestion such as liver, gallbladder and pancreas, as well as kidneys, bladder and spleen are also included. On the front of this cavity are only muscles, subcutaneous or stored fats and skin. Above it is a membrane, a layer of muscle that bridges the lower part of the rib cage and provides a ceiling in the shape of a dome for the cavity. Below, Thebdominopelvic cavity is contained in the pelvis around it, which forms a cage of bones that is open forward, and supported the pelvic floor muscles.

EngapThe sment of the abdominal cavity is a membrane lining known as the peritoneum. This lining consists of a leaf of single -layer mesothelial cells held by the vaginal tissue, which is made of the same fibers found in bindings and tendons. The entire membrane is only a few microns strong and not only surrounds the cavity as a whole, but also the individual organs contained inside.

that surrounding the cavity is known as a parietal peritoneum. It is attached to the wall of the abdominal muscles around its inner surface. The second layer known as the visceral peritoneum covers the organs inside. However, some organs, like the kidneys, sit between the two layers and are therefore referred to as retroperitoneal.

near the upper part of the abdominal cavity is the lowest part of the esophagus that descends from the thoracic cavity and pierces the membrane. This leads to the stomach, which then leads to small and ultimately large intestines, most of which are contained in the cavity. Adjacent to the stomach are the liver, gallbladder and pancreas, all of which support tRacing, as well as spleen, immune system and kidneys, urinary organs.

BottomMost Part of the cavity contains the lower part of the large intestine, which ends with a concrete, bladder and urinary blood vessels and organ reproduction. It is surrounded by pelvic bones: Ilium, ischium and pubis. Not only these bones, which protect the organs inside but the pelvic floor muscles, are important for the pelvic cavity structure. These muscles pass through the bottom of the pelvis, and in addition to their urine, excretors and sexual function, they form the "floor" that hold the organs at the top of the pelvis.
