Small intestine, Other Subject

The chyme enters the small intestines where all the nutrients are absorbed through the microscopic finger like villi on the lining of the small intestines. Vitamins and minerals pair up with carbohydrates, fats and proteins to be absorbed. Eighty percent of the digestive tract's absorption of nutrients takes place within the small intestine. It begins at the stomach and ends at the large intestine.

There are three important regions in the small intestine, namely:

a) Duodenum- which not only receives chyme but also digestive secretions.

b) Jejunum-site where most chemical digestion and nutrient absorption occurs.

c) Ileum-absorption continues. The spincter muscle controls the amount of chyme passing to large intestine.
