For transport, nutrients commonly rely upon: 1  Lipids – undergo passive or simple diffusion. 2  Short-chain fatty acids – diffusion. 3  Amino acids – primary active transport. 4  Glucose – secondary active transport. 5  Fructose – facilitated diffusion.

The small intestine is made up of three parts: 1  the duodenum (pronounced: due-uh-DEE-num), the C-shaped first part. 2  the jejunum (pronounced: jih-JU-num), the coiled midsection. 3  the ileum (pronounced: IH-lee-um), the final section that leads into the large intestine.

The large intestine is made up of three parts: 1  The cecum (pronounced: SEE-kum) is a pouch at the beginning of the large intestine that joins the small intestine to the large intestine. This transition area allows food to travel from the small intestine to the large intestine. The appendix, a small, hollow, finger-like pouch, hangs off the cecum. Doctors believe the appendix is left over from a previous time in human evolution. It no longer appears to be useful to the digestive process.

Functions of the small intestine. The small intestine is the part of the intestines where 90% of the digestion and absorption of food occurs, the other 10% taking place in the stomach and large intestine. The main function of the small intestine is absorption of nutrients and minerals from food. Digestion involves two distinct parts.

From the small intestine, food that has not been digested (and some water) travels to the large intestine through a valve that prevents food from returning to the small intestine. By the time food reaches the large intestine, the work of absorbing nutrients is nearly finished.

The Small Intestine. The small intestine is the part of the gastrointestinal tract between the stomach and the large intestine where much of the digestion of food takes place. The primary function of the small intestine is the absorption of nutrients and minerals found in food. Intestinal villus: An image of a simplified structure of the villus.

Food is the body's fuel source. The nutrients in food give the body's cells the energy and other substances they need to operate. But before food can do any of these things, it has to be digested into small pieces the body can absorb and use. Almost all animals have a tube-type digestive system in which food enters the mouth, passes through a long tube, and exits as feces (poop) through the anus.

Some of the disorders of the small intestine include: 1  Obstruction of the small intestine. 2  Infections including Giardiasis, Ascariasis, Tropical sprue, Tape worm infestation etc. 3  Small intestine cancer.

Chyme is then squirted down into the small intestine, where digestion of food continues so the body can absorb the nutrients into the bloodstream. The Small Intestine.
