Detailed explanation-1: -The small intestine is actually the longest segment of the gastrointestinal tract-the long, continuous pathway that food travels through your digestive system. In the small intestine, food is broken down into liquid and most of its nutrients are absorbed.
Detailed explanation-2: -The small intestine is so long because it needs a maximum amount of surface area to increase digestion and nutrient absorption. The small intestine is where your body breaks down food and takes up all the possible nutrients from it before discarding the rest as waste.
Detailed explanation-3: -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-4: -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.
