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.
The ileum: The final section of the small intestine. It is about 3 m long, and contains villi similar to the jejunum. It absorbs mainly vitamin B12 and bile acids, as well as any other remaining nutrients. The ileum joins to the cecum of the large intestine at the ileocecal junction.
