Small Intestine

The small intestine is a long, tube-like organ located in the abdomen. It is part of the digestive system and its unique design helps to break down and absorb food. Nutrients are absorbed through the highly folded walls of the small intestine, which are lined with millions of finger-like projections called villi. These provide a large surface area for the absorption of food molecules. The small intestine also contains mucus-producing glands which aid digestion and protect the lining of the intestine. The small intestine plays an important role in the digestion and absorption of nutrients and is essential for the proper functioning of the body.
