What is Claims Adjudication? An insurance claim must meet all eligibility requirements before it can be paid. Insurance companies use claims adjudication to determine whether they will cover a procedure or if the policyholder must pay out of pocket.
The lining of the small intestine has tiny, finger-shaped tissues (villi). These raised tissues greatly increase the surface area of the intestine, which absorbs calories and nutrients from food. The small intestine consists of three parts. The first part, called the duodenum, connects to the stomach. The middle part is the jejunum. The third part, called the ileum, attaches to the colon.
Small Intestine: Site of Nutrient Absorption. The small intestine, which is approximately 10 feet long, is the site of most nutrient absorption. The inside surface of this organ contains numerous folds, covered by very thin, long projections on the inside of the intestinal wall called villi.
