What are the parts that make up large intestine?

The large intestine (also called the large bowel) is the final portion of the digestive tract, where water is absorbed from the ingesta and faecal matter is produced and stored. It lies in the abdominal cavity and extends from the ileocecal valve to the anus.

The parts that make up large intestine are:

1. Cecum: The cecum is the first part of the large intestine and is located in the right lower quadrant of the abdomen. It is a pouch that receives the contents from the small intestine through the ileocecal valve.

2. Ascending colon: The ascending colon is the second part of the large intestine and extends from the cecum to the right colic flexure. It ascends on the right side of the abdomen.

3. Right colic flexure: The right colic flexure is a bend where the ascending colon changes direction and turns to the left.

4. Transverse colon: The transverse colon is the third part of the large intestine and extends from the right colic flexure to the left colic flexure. It is located across the abdomen.

5. Left colic flexure: The left colic flexure is a bend where the transverse colon turns downward to the left.

6. Descending colon: The descending colon is the fourth part of the large intestine and extends from the left colic flexure to the sigmoid colon. It descends on the left side of the abdomen.

7. Sigmoid colon: The sigmoid colon is the fifth and final part of the large intestine before the rectum. It has a shape of an S and is located in the lower left quadrant of the abdomen.

8. Rectum: The rectum is the final straight portion of the large intestine before it joins with the anus. It stores faecal matter and helps with defecation.

9. Anus: The anus is the opening at the end of the digestive tract through which faecal matter is expelled from the body.
