Small intestine is divided three parts, which are duodenum, jejunum and ileum which helps in absorption of nutrients from the digested food, while Large intestine has four parts, which are colon, rectum, caecum and anal canal which helps in absorption of water and electrolytes, as well in production of vitamins like B ...

The duodenum is the first part of the small intestine (5-7 m), followed by the jejunum and ileum (in that order); it is also the widest and shortest (25 cm) part of the small intestine. The duodenum is a C-shaped or horseshoe-shaped structure that lies in the upper abdomen near the midline (see the image below).

The intestines are vital organs in the gastrointestinal tract of our digestive system. Their functions are to digest food and to enable the nutrients released from that food to enter into the bloodstream. Our intestines consist of two major subdivisions: the small intestine and the large intestine.

Villi in the small intestine. Millions of tiny finger-like structures called villi project inwards from the lining of the small intestine. The large surface area they present allows for rapid absorption of digestion products.

Anatomy of the large intestine. The large intestine is approximately 1.5m long and comprises the caecum, colon, rectum, anal canal and anus (Fig 1). The structure of the large intestine is very similar to that of the small intestine (see part 4), except that its mucosa is completely devoid of villi.

Your large intestine is about five feet (or 1.5 meters) long.

large intestine. The long, tube-like organ that is connected to the small intestine at one end and the anus at the other. The large intestine has four parts: cecum, colon, rectum, and anal canal.

The main functions of the small intestine are secretion and absorption. The epithelial cells of the small intestine secrete enzymes which digest chyme into the smallest particles, making them available for absorption.

Its job is to absorb most of the nutrients from what we eat and drink. Velvety tissue lines the small intestine, which is divided into the duodenum, jejunum, and ileum. The large intestine (colon or large bowel) is about 5 feet long and about 3 inches in diameter. The colon absorbs water from wastes, creating stool.

The large intestine (colon or large bowel) is about 5 feet long and about 3 inches in diameter. The colon absorbs water from wastes, creating stool. As stool enters the rectum, nerves there create the urge to defecate.

Jejunum. The jejunum is the middle of the three parts of the small intestine between the duodenum and ileum.

There are three main substances that the small intestine receives: bile, pancreatic enzymes and alkaline juice (HCO3-). Bile serves an important role in lipid digestion, and is secreted from the gallbladder into the common bile duct, in response to CCK.

The bowel is part of the digestive system. It is made up of the small bowel (small intestine) and the large bowel (colon and rectum). The small bowel is longer than the large bowel but it gets its name from the fact it is much narrower than the large bowel. Cancer is more likely to develop in the large bowel.

The jejunum is the middle section of the small intestine. It has a lining which is designed to absorb carbohydrates and proteins. The inner surface of the jejunum, its mucous membrane, is covered in projections called villi, which increase the surface area of tissue available to absorb nutrients from the gut contents.
