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 absorption of nutrients and water is extremely efficient. Because being an endothermic organism necessitates high metabolic rates, mammals must obtain every nutrient from their diet. In conclusion, an extremely long digestive tract provides room for complete digestion and maximum absorption of nutrients.
Detailed explanation-4: -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. The small intestine is part of the digestive system.
Detailed explanation-5: -The small intestine is the most important organ of the digestive system as it serves both, for digestion and absorption. It receives two digestive juices; the bile and the pancreatic juice in the duodenum. These two juices virtually complete the digestion of starch, proteins, carbohydrates, etc.
