But just because you have a gym membership that you actually use doesnât mean you canât also have a few things at home for doing other types of workouts that you donât have time for at the gym, or for those days that you just canât make it out the front door.
The inside wall of the small intestine needs to be thin, with a really big surface area. This allows absorption to happen quickly and efficiently. If the small intestine had a thick wall and a small surface area, a lot of digested food might pass out of the body before it had a chance to be absorbed.
The increased surface area will allow the small intestine to absorb most of the nutrients of the body. There are blood vessels and vessels contained a fluid called lymph inside the villi. Fat-soluble vitamins and fatty acids are absorbed into the lymph system.ood is moved along by peristalsis. Digestion is completed in the small intestine.   Most chemical digestion and absorption of food occurs in the small intestine. The small intestine is a long, coiled organ about one inch in diameter. The stomach connects with the duodenum, the first part of the small intestine.
