It starts in the right iliac region of the pelvis just at or below the right waist where it is joined to the bottom end of the small intestine.

Large intestine anatomy. The mesentery also supplies the large intestine with blood from the superior and inferior mesenteric arteries. The large intestine consists of the cecum colon rectum and anal canal. Large intestine posterior section of the intestine consisting typically of four regions.

Caecum Vermiform appendix Transverse Descending and Sigmoid. The basic function of the large intestine is to absorb water and a few other products from. The large intestine also known as the large bowel is a 15 meter muscular tube that extends from the cecum to the rectumIt has three outer longitudinal muscular layers called taenia coli which are about 30 cm shorter than the length of the large bowel causing characteristic sacculations interrupted by incomplete rings called haustra 1The large bowel is divided into the following parts.

Anatomically the colon can be divided into four parts Ascending. Some parts of it are intraperitoneal while others are retroperitoneal. It is divided into two parts the small intestine and the large intestine.

Next the distal intestine stores fecal matter until its expulsion. Although shorter than the small intestine in length the large intestine is considerably thicker in diameter thus giving it its name. Mucosa submucosa muscular innersubmucosa muscular inner circular and outercircular and outer longitudinal and serosalongitudinal and serosa.

Anatomy of the Large Intestine The large intestine commences at the cecum as a blind pouch below the termination of the small intestine. The large intestine includes the following sections. The large intestine is subdivided into four main regions.

The colon large intestine is the distal part of the gastrointestinal tract extending from the cecum to the anal canal. Velvety tissue lines the small intestine which is divided into the duodenum jejunum and ileum. The colon The colon large intestine is a distal part of the gastrointestinal tract extending from the caecum to the anal canal.

The cecum colon rectum and anal canal. The large intestine is the portion of the intestine that extends from the ileocecal valve to the anus. It hooks around usually encircling the convolutions of the small intestine and terminates at the rectum.

The intestine forms a major part of the digestive tract in humans. The large intestine is responsible for processing indigestible food material chyme after most nutrients are absorbed in the small intestine. The intestine is that portion of the digestive tract that runs between the stomach and the anus.

Together they form the widest and shortest part of the digestive tract. Transverse and sigmoidTransverse and sigmoid colons are suspended bycolons are suspended by their mesocolonstheir mesocolons. The large intestine colon or large bowel is about 5 feet long and about 3 inches in diameter.

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 large intestine consists of the cecum appendix ascending colon transverse colon descending colon rectum and anal canal. Fecal matter entering the large intestine from the ileum passes into the cecum before being pushed superiorly into the ascending colon.

The cecum colon rectum and anal canal. Most of the large intestine is located inside the abdominal cavity with the last portion residing within the pelvic cavity. The large intestine is named for its relatively large diameter not its length.

Our large intestine consists of 4 major regions. 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. 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.

These sections form an arch which encircles the small intestine. The cecum colon rectum and anus. Anatomically the colon can be divided into four parts ascending transverse descending and sigmoid.

The large intestine is held in place and attached to the abdominal wall by a sac-like structure called the mesentery. The large intestine is a 1 to 15 meter continuation of the ileum extending from the ileocecal junction to the anus. The colon averages 150cm in length.

First the proximal large intestine is responsible for absorbing water and electrolytes. 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 receives digested food from the small intestine from which it absorbs water and electrolytes to form faeces.

The cecum is a pouch-like dead-end passage that branches inferiorly from the end of the ileum. The cecum the colon the rectum and the anus.
