What is the human abdominal cavity?
You probably have heard the expression, "the abdomen of man"? But if you can determine exactly what it is? Where it begins and where it ends, this is the cavity? What's in this cavity is and why it is called. Although the last is not difficult to guess.
Let us try in this article to define this concept more clearly. After all, medicine - it is, of course, not mathematics, but also science. And precision and certainty she did not interfere.
Thus, the abdominal cavity - is one of the cavities of the human body. A cavity in the body enough. Starting from such large, as the abdominal and thoracic cavities and ending with such small as the mouth or nose.
All human body is divided into two cavities: thoracic and abdominal. And the boundary between the cavity - the diaphragm. Above the diaphragm is the thoracic cavity. Below it - the abdominal cavity.

All human body is divided into two cavities: thoracic and abdominal. And the boundary between the cavity - the diaphragm. Above the diaphragm is the thoracic cavity. Below it - the abdominal cavity.
That is one of the boundaries of the abdominal cavity we found out - the top. It is formed by the diaphragm. What is the aperture you will soon be able to read the relevant article on this site.
The front and side walls of the abdominal cavity - it is nothing like the muscles and tendons of the front and side walls of the abdomen. A back - the spine and back muscles.
Bottom abdominal cavity is formed by the bones and muscles of the pelvis.
The entire abdomen gently and carefully lined with a special shell - peritoneum. The peritoneum has two sheets. One piece of lining the entire abdominal cavity inside, covering an abdominal wall. It is called the parietal peritoneum (from the Latin word parietis - wall). The second sheet covers the organs located within the abdominal cavity. And this piece is called the peritoneum visceral peritoneum (from the Latin word viscera - internal).
But the visceral peritoneum envelops not all the organs located in the abdominal cavity. Part bodies adjacent to back, visceral peritoneum are covered only on one side. This space between the parietal peritoneum covering the back wall of the abdominal cavity, and the visceral peritoneum is called the retroperitoneal space.
Bodies found in the pelvic area is also covered by peritoneum only on one side. This makes it possible to allocate another abdominal cavity - cavity of the pelvis.
That is, the peritoneum divides the abdomen into three cavity: peritoneum space (located in front), and retroperitoneal space (located posteriorly) and the pelvis (at the bottom).
