Small Intestine (Small Bowel)

The small intestine, or the small bowel, extends from the pyloric sphincter to the first part of the large intestine. It is 20 feet long and has three parts. The duodenum, the first part, receives food from the

stomach, bile from the liver and gall bladder, and pancreatic juice

from the pancreas. Food is digested in the duodenum and passes in peristaltic waves from the duodenum to the second part, the jejunum, which is about 8 feet long. The jejunum connects with the third sec­tion, the ileum, about 11 feet long, which is attached to the large in­testine.

In the wall of the entire small intestine are millions of tiny, finger- like projections called villi (singular: villus). It is through the capillary network of the villi that digested foods (simple sugars, amino acids, and fatty acids) pass to enter the bloodstream (absorption).

Large Intestine (Large Bowel)

The large intestine extends from the ileum to the anus. It is di­vided into four parts: caecum, colon, sigmoid colon, and rectum. The caecum, or the first part, is a pouch on the right side which is con­nected to the ileum by the ileocaecal sphincter (ring of muscles). The vermiform (worm-like) appendix hangs from the caecum; the appen­dix is a blind alley and has no function. The colon is about 5 feet long and has three divisions. The ascending colon extends from the caecum to the undersurface of the liver where it turns to the left (hepatic flex-

ure) into the transverse colon; the transverse colon passes horizontally to the left toward the spleen, and as it reaches the splenic region it turns downward (splenic flexure) into the descending colon. The sig­moid colon (resembling an S) is at the distal end of the descending colon and leads into the rectum. The rectum terminates in the lower opening of the gastrointestinal tract, the anus.

The large intestine receives the fluid by-products of digestion from the small intestine. Unabsorbed solid material is stored in the colon and water is reabsorbed into the bloodstream while the solid material travels along to eventually be eliminated from the body as faeces.
