Small Intestine - the longest part of the digestive tract. It is between the preceding stomach and followed by the large intestine. Vast majority of digestion and absorption of food takes place in the small intestine.
Small Intestine Has 3 Parts
The small intestine makes up more than 70% of the length and 90% of the surface area of the gastrointestinal tract and is made of 3 sections:
Absorption of Nutrients
Food from the stomach is allowed into the duodenum, and is pushed through the small intestine by a process of wavelike contractions called by the surrounding muscles.

The three major classes of nutrients that undergo digestion are proteins, lipids (fats) and carbohydrates:
