The duodenum is the shortest subdivision and is where most of the chemical digestion takes order. The jejunum and ileum are responsible for the assimilation of nutrients into the bloodstream. The modest intestine is comparatively narrow and has a declamatory surface region due to its legion folds and villi, which increase the area available for absorption.

The large intestine, also known as the colon, is the second part of the bowel. It is divided into respective sections: the cecum, ascend colon, transverse colon, descending colon, sigmoid colon, and rectum. The large intestine is wider than the small intestine and plays a all-important role in absorbing water and electrolytes from the remaining indigestible food affair, organize stool in the process.

Functions of the Bowel

The chief functions of the bowel are digestion, assimilation, and riddance. The small intestine breaks down food into smaller molecules that can be absorb into the bloodstream.
