The two primary roles of the digestive process are absorption and secretion. The role of absorption in the digestive system is vital to the body because without it, the vitamins, minerals, carbohydrates and other nutrients we consume could not be used. Absorption is the process by which the nutrients in food are passed on to the blood. The majority of absorption occurs in the small intestine, the digestive tract's primary organ.
After food passes through the stomach to the small intestines, it is turned into energy for the body to use. Absorption is made possible by the villi, small bristle-like protrusions in the mucosa. The mucosa is the moist tissue lining certain parts of the body's passages and organs. The villi act as channels through which the nutrients derived from digested foods can pass into the bloodstream and be carried to the rest of the body. The actual absorptionprocess is slightly different for each type of nutrient.

What is villi and what important structures do they contain?

Why drinking sufficient water is important in the absorption of the end products of digestion in the small intestine?
Drinking water is important because it helps to dissolve foods so therefore they can be soluble molecules that can be absorbed into the bloodstream by villi. Villi are finger like features in the small intestine which increase the surface area.
What are the functions of the small intestine?
The main and most important function of the small intestine is * absorption. While digestion of food practically starts in the mouth (mechanical digestion, enzymatic digestion), and continues in the stomach (digestion of proteins), the small intestine finished the digestion (others then protein), and absorb everything the body needs. Leaving the large intestine to deal with the absorption of water, and as a place for some bacterial activity (certain vitamins). The small intestine also * transport received the chime from the stomach, its peristaltic movement further it (what's left of it) down to the large intestine. It secrets * enzymes, digestive juices necessary for the digestion/absorption/pH regulation. * It receives other necessary enzymes, chemicals from other organs (bile ect.) which it utilises in the above process.

The small intestines are important in the digestive system. There are small finger like structures in the Small intestines called villi, these villi extract the nutrients and take it into the blood stream. Without the small intestines you would not be able to extract nutrients from the food.
