The abdomen of humans is a part of the body between the pelvis and the chest. In human anatomy, the abdomen extends from the diaphragm at the bottom of the chest to the true pelvis at the pelvic boundary. So today, let’s analyze the anatomic photograph and photo of the abdominal body with you, let’s take a look together. I hope it can help you.

The human anatomy diagram (Humananatomy) is an analytical diagram of the human structure from the anatomical perspective, based on the anatomical posture. In order to show the shape, location, and internal relationship of various parts and structures of the body, it is necessary to establish a standard posture first. In describing all postures, this standard posture is taken as the standard.

The human body contains many organs, and each organ plays a necessary function. Let’s take a look at the anatomic photograph of the abdominal body and the picture below.

The retroperitoneum peritoneum is the largest in total area and the most complexly distributed serous membrane in the body, composed of mesothelium and a small amount of connective tissue, thin and smooth, appearing translucent. The retroperitoneum located on the inner surface of the abdominal and pelvic walls is called the parietal peritoneum or retroperitoneal wall layer. The part covering the superficial layer of the abdominal and pelvic visceral organs is called the visceral peritoneum or retroperitoneal visceral layer. The visceral peritoneum and the parietal peritoneum are continuously and gradually transitioning to each other, forming irregular and irreversible spaces, known as the peritoneal cavity peritonealcavity. The male peritoneal cavity is a closed cavity; the female peritoneal cavity communicates with the external environment through the abdominal orifice of the fallopian tubes, the uterus, and the vagina. The parietal peritoneum is thicker and there is a layer of loose connective tissue between the abdominal and pelvic walls, known as the retroperitoneal outer tissue. The retroperitoneal outer tissue under the posterior and anterior abdominal walls contains a large amount of adipose tissue. The visceral peritoneum is closely adjacent to the superficial layer of visceral organs and can be considered as part of the human organ from both the tissue structure and functional perspectives, such as the serous membrane of the most superficial layer of the stomach and intestinal cavity is the visceral peritoneum.

Under normal conditions, a small amount of serous fluid (100~200ml) is produced in the retroperitoneum, which has the effect of lubricating and reducing friction between visceral organs. The retroperitoneum also has absorbent properties, capable of digesting and absorbing liquids and gases in the peritoneal cavity. The absorbent capacity of the upper part of the retroperitoneum is stronger than that of the lower part, hence patients with abdominal inflammation or postoperative patients often adopt a semi-recumbent position to allow harmful fluids to flow to the lower abdomen, thereby alleviating the retroperitoneum’s digestion and absorption of harmful substances. The retroperitoneum and the serous fluid in the peritoneal cavity contain a large number of macrophages, which have a defensive function. The retroperitoneum also has strong repair and reconstruction capabilities. The adhesive effect of the methylcellulose metabolized in the serous fluid can promote the healing of wounds and the limitation of inflammation. However, if surgical operations are rough, this effect may also lead to complications such as fibrous adhesions in the intestinal loops. The structures produced by the retroperitoneum, such as tendons and mesenteries, also have the functions of fixation and adaptation of visceral organs. In summary, the retroperitoneum has multiple functions such as metabolism, digestion and absorption, protection, adaptation, and repair.
