They sense the presence of food, complete the digestion process and absorb the digested food. They contract to push the undigested food to the large intestine. Key Questions What is the purpose of the villi found in the small intestine? Answer: To absorb nutrients and the complete breakdown of food.

Factors of its structure that help it function include Large surface area provides more surface area for exchange to take place Thin wall reduces the distance that materials need to move Moist assists the transport of materials across the exchange surface The process that the nutrients move into the villi is diffusion.

What is the role of villi in digestion? How is food absorbed? While individually the villi and crypts are obviously pretty miniature by themselves, together they provide a huge amount of surface area for nutrients to be absorbed into your bloodstream—almost the surface area of an entire football field, given that your small intestine itself is about 23 feet long.

There are several different medical conditions that can cause damage to your intestinal villi. In celiac disease , consumption of the protein gluten found in the grains wheat, barley, and rye triggers your immune system to attack your intestinal villi and wear them down a process called villous atrophy. Inflammatory bowel disease , which includes Crohn's disease, also can cause your villi to erode, as can lymphoma and certain infections, such as an infection involving the parasite Giardia.

There are certain diseases that can damage villi and render them unable to absorb the nutrients your body needs. One of these is Celiac disease. A person with this disease will produce antibodies in response to ingested gluten , a protein found in wheat flour. These antibodies can attack the lining of the small intestine which can then lead to the damage. With damaged villi, a person may not be able to absorb nutrients in their body and malnutrition can result.

One prominent cause of villi damage is celiac disease, a disorder caused by an immune reaction to gluten. When people with celiac disease eat gluten, the inflammation blunts the villi, making them unable to participate effectively in the breakdown and absorption of nutrients. Other conditions, such as Crohn's disease, can also affect the small intestine and lead to malabsorption of nutrients.
