Colon Rectum

Intestine Rectum is the final section of the large intestine, which plays an important role in the process of digestion and excretion. It is located between the sigmoid colon and the anus, has a length of about 12 cm and a diameter of about 4-5 cm.

The main function of the rectum is the temporary storage of feces before defecation. Feces enter the rectum from the sigmoid colon and are then evacuated through the anus. This process is controlled by the muscles of the anus and spinal cord.

The rectum has three layers of the wall: mucous, muscular and external. The mucous layer is composed of epithelial cells and contains many glands that secrete mucus to lubricate the intestinal walls and facilitate the passage of stool. The muscle layer consists of two layers of smooth muscle that control the movement of feces. The outer layer consists of connective tissue and provides a protective covering for the rectum.

Pathologies of the rectum can lead to various diseases, such as hemorrhoids, anal fissures, anal fistula, etc. Various methods are used to diagnose and treat these diseases, including proctological examination, rectoscopy, colonoscopy and others.

In conclusion, the Rectum is an important organ for the process of excretion and control of feces in the body. Its health and functioning are of great importance for a person's overall health.

The rectum is considered the final part of the large intestine, and it includes only 12 centimeters in length - starting from the rectum and ending with the anus, in other words, the anus. Feces and gases pass through the rectum. The term itself comes from the Latin word “recens”, which means “pure”. In the human body, it performs a number of important functions: responsible for the formation and removal of feces; helps to absorb liquid during a heavy diet, as well as transport and digest food within the body.

Often this intestine is up to 22-25 cm long. Its structure is similar to the structure of the large intestine. However, this part consists of muscle tissue. With its help, the process of throwing out feces, the so-called defecation, occurs. In addition to excreting feces, during this activity the glands secrete a mucous secretion that protects the intestines from damage and irritation. Also in the rectum are the largest glands in our body - rectal glands. They excrete their secretions in the form of urine and feces, thereby exerting an analgesic effect on the body.

The structure of the rectum includes only two parts: the ampulla and the ampuloduodenal zone. The ampoule is formed by muscle tissue and serves as a place for the accumulation of feces. In a healthy

Rectum (rectum - lat.) / Rectum - the final section of the large intestinal tube (interstnum), stretching from the sigmoid colon to the superior depression. The content of the associative helmaroxa (peristaltic coulter) passes into it, but in an incomplete version. The length is usually 13-15 cm in men and 9-11 in women. The terminal compartment is connected to the hindgut (rectal sphincter). Such fecal masses pass through the rectum during the time the action of the feces ends.

Until the age of twelve, the presence of sexual “breathing” comes from the sigmoid part of the intestine. This is a private gase that was bubbling in the air, as well as the corresponding strand present in primitive products. Under conditions of three half-periods, defecation occurs in

Rectum: Overview and Functions

The rectum is the terminal part of the large intestine, which plays an important role in the process of digestion and the evacuation of waste from the body. This segment of intestine is approximately 12 centimeters in length and is located between the sigmoid colon and the anus.

The structure and location of the Colon Rectum make it a key element in the digestive system. It is located in the pelvic cavity and is usually straight, although some people may have a slight curve. The rectum is surrounded by various anatomical structures, including the anterior vaginal wall in women and the prostate in men.

One of the main functions of the Rectum is to store feces before defecation. During the digestion process, undigested food debris moves through the colon and gradually accumulates in the rectum. Here they are temporarily retained until defecation activity is initiated.

The rectal segment, associated with the rectum, is closely related to the process of defecation. During the act of defecation, contraction of the muscles of the rectum and accompanying muscles of the pelvic floor helps move feces towards the anus for subsequent removal from the body. In addition, nerve receptors in the walls of the rectum play an important role in sensing sensations of pressure and filling, and transmit corresponding information to the central nervous system.

The rectum is also involved in the process of regulating the body's water balance. Limited absorption of water and electrolytes can occur through the walls of the rectum, which allows the body to effectively regulate the consistency of stool.

It is important to note that the Rectum is an area where various diseases and conditions can occur. Colorectal cancer is one of the most common types of cancer of the digestive system. Other common problems associated with the rectum include hemorrhoids, anal fissures and inflammatory diseases such as proctitis and proctosigmoiditis.

In conclusion, the Rectum plays an important role in the process of digestion and bowel movements. It serves as a temporary storage place for feces and is actively involved in their removal from the body. The structure and function of the rectum are important to a person's overall health and well-being. Understanding its anatomy and role in the digestive system helps maintain optimal function of this organ and prevent the occurrence of various diseases.
