It receives digested food from the small intestine from which it absorbs water and electrolytes to form faeces.

Anatomy of the intestines. Its job is to absorb most of the. The small intestine has three segments. It has a surface area of over 200 meters.

As compared to the small intestine the large bowel is wider. It frames the small intestine on three sides. The mucous membrane lining the intestinal wall of the small intestine is thrown into transverse folds called plicae circulares and in higher vertebrates minute fingerlike projections known as villi project into the cavity.

But is only 15 meters in length which is around one fifth of the length of the intestinal canal. In living humans the small intestine alone measures about 6 to 7 meters long. After death this length can increase by up to half.

These structures greatly increase the area of the secreting and absorbing surface. The small intestine small bowel is about 20 feet long and about an inch in diameter. The small intestine starts at the pylorus of the stomach and ends at the cecum of the large intestine.

The large intestine consists of the cecum ascending colon transverse colon descending colon and sigmoid colon. The ileocecal valve located at the opening between the ileum and the large intestine controls the flow of chyme from the small intestine to the large intestine. The main function of the small intestine is continued digestion and absorption of nutrients.

The intestines include the small intestine large intestine and rectum. The small intestine is made up of the duodenum jejunum and ileum. The large intestine is the terminal part of the alimentary canal.

The colon large intestine is the distal part of the gastrointestinal tract extending from the cecum to the anal canal. The duodenum the jejunum and the ileum. These sections form an arch which encircles the small intestine.

In humans the large intestine begins in the right iliac region of the pelvis just at or below the waist where it is joined to the end of the small intestine at the cecum via the ileocecal valve. Anatomically the colon can be divided into four parts ascending transverse descending and sigmoid. Gross anatomy the intestines are located inferior to the stomach in the abdominal body cavity.

Together with the esophagus large intestine and the stomach it forms the gastrointestinal tract. It then continues as the colon ascending the abdomen across the width of the abdominal cavity as the transverse colon and then descending to the rectum and its endpoint at the anal canal. The cecum the colon the rectum and the anus.

The primary function of this organ is to finish absorption of nutrients and water synthesize certain vitamins form feces and eliminate feces from the body. They are connected to the posterior wall of the abdomen by the mesentery a thin vascular membrane.
