In this article we shall examine the anatomy of the small intestine its structure neurovascular supply and clinical correlations.

Anatomy of intestines. Anatomy of the Small Intestine The small intestine is a convoluted tubular organ extending from the pylorus to the ileocecal valve occupying the central and lower parts of the abdominal cavity. In human anatomy the intestine bowel or gut. The small intestine small bowel is about 20 feet long and about an inch in diameter.

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. It is divided into two parts the small intestine and the large intestine. The small intestine forms a major part of the human intestine with a length of around six meters.

The small intestine is divided into the duodenum jejunum and ileum. Mostly circumscribed by the large intestines it is divided into three segments. The large intestine is the final section of the gastrointestinal tract that performs the vital task of absorbing water and vitamins while converting digested food into feces.

Although shorter than the small intestine in length the large intestine is considerably thicker in diameter thus giving it its name. The duodenum jejunum and ileum. Duodenum which is continuous with the gastric pylorus where the common bile duct ductus choledochus and the pancreatic duct lead into the major.

The rest of the colon is. The cecum the colon the rectum and the anus. éntera is the segment of the gastrointestinal tract extending from the pyloric sphincter of the stomach to the anus and as in other mammals consists of two segments the small intestine and the large intestine.

It extends from the stomach to the large intestine and consists of 3 major regions. Together the small and large intestines run from the end of the stomach to the anus. The cecum the colon the rectum and the anus.

The large intestine is subdivided into four main regions. The large intestine is a 1 to 15 meter continuation of the ileum extending from the ileocecal junction to the anus. Duodenum jejunum and ileum.

The duodenum receives partially digested food from the stomach bile from the liver and gallbladder and pancreatic juice from the pancreas. Some parts of it are intraperitoneal while others are retroperitoneal. It can be found in the center of the abdominal cavity.

Together these can extend up to six meters in length. The small intestine is made up of thee sections including the duodenum the jejunum and the ileum. The duodenum jejunum and ileum.

The colon is also called the large intestine. Anatomically the small bowel can be divided into three parts. Its job is to absorb most of the.

Anatomy of the Intestines Although digestion of proteins carbohydrates and lipids may begin in the stomach it is completed in the intestine. The intestines include the small intestine large intestine and rectum. Intestine tubular part of the alimentary canal that extends from the stomach to the anus.

The duodenum has both intraperitoneal and retroperitoneal parts while the jejunum and ileum are entirely intraperitoneal organs. 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. The intestines absorb nutrients and vitamins and are part of the gastrointestinal GI tract.

Most of the large intestine is located inside the abdominal cavity with the last portion residing within the pelvic cavity. The ileum last part of the small intestine connects to the cecum first part of the colon in the lower right abdomen. Fig 1 The anatomical divisions of the small intestine.

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 large intestine is subdivided into four main regions. All three parts are covered with the greater omentum anteriorly.

The intestine is the site of most chemical digestive processes and the place where digested food materials are either absorbed for use by the body or collected into feces for elimination. The absorption of nutrients water and electrolytes from food and drink also occur in the intestine. 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.

On its distal far end the ileumthe last segment of the small intestineconnects to the large intestine colon. The small intestine is located intraperitoneally and is divided anatomically into the. The small intestine is about 1 inch in diameter and about 10 feet long in a living body.
