The small intestine extends from the pylorus of the stomach to the caecum . It is attached along it's whole length to the dorsal abdominal wall by mesentry. The mesentry is relatively long for its most part, giving the small intestine a great deal of mobility. The small intestine produces enzymes for digestion of protein, carbohydrate and fat and absorbs the products of their digestion. Enzymes are produced by glands in the intestinal wall and the pancreas. The gall bladder produces bile which emulsifies fats for digestion. Absorption is facilitated by ridges in the small intestine and by the presence of villi and microvilli.

The small intestine extends from the pylorus of the stomach to the caecum. The small intestine recieves chyme from stomach.  Most chemical degradation of the chyme and absorption takes place in the small intestine. Fats are exclusively broken down in this part of the alimentary tract. Carbohydrates and proteins that are not degraded in the small intestine are available for microbial fermentation in the large intestine. The small intestine produces enzymes for digestion of protein, carbohydrate and fat and absorbs the products of their digestion. Enzymes are produced by glands in the intestinal wall and the pancreas. The gall bladder produces bile which emulsifies fats for digestion.
