What is the function of small intestines?
Answer The small intestine is responsible for absorbing most of the nutrients found within your food. By the time ingested food reaches the small intestine, it has been mechanically broken down into a liquid. As this liquid flows across the inner surface of the small intestine (which has many small folds to increase the surface area), nutrients within the food come into contact with the many small blood vessels which surround the small intestine. This blood then leaves the small intestine, carrying away nutrients, water electrolytes, vitamins, minerals, fats and medications to the entire body. It can take three to six hours for a meal to pass from one end of the small intestine to the other, and that is dependent on the makeup of the food passing through; meals containing a lot of fiber move more quickly. Absortion of nutients, vitamines , minerals and some water. Also propulsion of food along the intestinal lumen.
Functions of the small and large intestine?

It can take three to six hours for a meal to pass from one end of the small intestine to the other, and that is dependent on the makeup of the food passing through; meals containing a lot of fiber move more quickly. while the large intestine:is the thick, lower end of the digestive system, containing the appendix, colon and rectum. Its principle function is to reabsorb water and maintains the fluid balance of the body. Certain vitamins are also taken in through the large intestinal wall. Further down the intestine, in the rectum, faeces are stored waste before it is eliminated. Another function is to process undigestible material (fibre), which makes up the bulk of the waste products.
Why does extra blood flow through intestine and stomach wall during and after meal?
to help with digestion
