Left Colon Flexure

The left colonic flexure is the flexure of the colon that lies to the left of the midline of the abdomen and passes through the spleen. This bend is an important anatomical formation, as it provides a connection between the colon and the spleen, and also serves the function of protecting the internal organs.

The anatomical location of the left flexure of the Colon may vary depending on the individual characteristics of the body. However, in most cases, the left flexure of the Colon is located at the level of the 1st or 2nd lumbar vertebrae, and its length is approximately 5-6 cm.

Structurally, the flexure of the left colon consists of several layers of tissue. At the top is the peritoneum, which covers the intestines and provides its protection. Below the peritoneum there is a muscular layer that allows intestinal movement. Beneath the muscularis mucosa is the mucous membrane, which lines the inner surface of the intestines and contains many glands that produce mucus.

The left flexure of the Colon is important for the normal functioning of the body. It provides a connection between the spleen and colon, allowing metabolic products that have been processed in the stomach and intestines to pass through the blood. In addition, the left bend of the Colon protects the internal organs from damage and injury.

In conclusion, the left flexure of the Colon is an important anatomical element that plays an important role in the functioning of the body. Its location and length may vary depending on the individual body structure, but its functions remain the same.



Colonic flexure is a type of bowel bending in the shape of the Latin letter “S” to the left. This bend is located in the mid-gut and is formed by intertwining with the small intestine and stomach.

One of two bends of the colon, occurring in 80-90% of cases. Another flexure located on the opposite side of the intestine is the right flexure of the colon. And, despite the fact that the right bend of the intestine is significantly larger in size, it is not so important for the normal functioning of the gastrointestinal tract. This is explained by the fact that the left spleen, in turn, is smaller than the right and its influence on the functioning of the colon is limited. The size of the spleen depends on the amount of gall bladder substance and the composition of the blood. That is why the right bend is greater than the left

The left flexure of the colon is the portion of the digestive tube where the inferior iliac artery is located. It is located near the joint of the second lumbar head of the muscle that connects the colon to the rectum. At the top of the colon, the organ also contains blood vessels and lymph nodes, which provide additional protection against harmful substances from food
