The small intestine extends from the pylorus of the [[Forestomach - Anatomy & Physiology|stomach]] to the [[Caecum - Anatomy & Physiology|caecum]]. The small intestine recieves chyme from the [[Forestomach - Anatomy & Physiology|stomach]]. It is the main site of chemical degradation and absorption of chyme. 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 - Anatomy & Physiology|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 - Anatomy & Physiology|pancreas]]. The [[Gall Bladder - Anatomy & Physiology|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.
