Detailed explanation-1: -It takes up to five hours for the small intestine to process a single meal through its 22-foot length. During that time, it systematically breaks food down and absorbs 95% of its nutrients. It coordinates with the stomach, pancreas and gallbladder to cue digestive juices when food is present.
Detailed explanation-2: -The small intestine has three parts: the duodenum, jejunum, and ileum. It helps to further digest food coming from the stomach. It absorbs nutrients (vitamins, minerals, carbohydrates, fats, proteins) and water from food so they can be used by the body.
Detailed explanation-3: -The lining of the small intestinal mucosa is very highly specialized for maximizing digestion and absorption of nutrients. The lining is highly folded to form microscopic finger-like projections called villi which increase the surface area to help with absorption.
