The small intestine plays a large role with vitamin absorption. Many of us are probably not sure exactly how this happens. Here are a few informative points of how absorption occurs in the small intestine.
The small intestine consists of three regions: the duodenum, jejunum, and ileum. Digestion occurs primarily in the duodenum. The jejunum and ileum have a primary function of absorption.
The small intestine has the perfect anatomy for absorption. The surface villi (small finger like projections) contain epithelial cells with brush border microvilli that allow for increased surface area. This increases the absorption ability. Nutrients are absorbed across the epithelium villi and are carried to the bloodstream through capillaries. Once the nutrients are absorbed into the bloodstream, they are carried to where they perform their functions.
