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 colon, which is the first 4 feet or 5 feet of the large intestine, is part of the body's digestive system. It has the job of absorbing water from waste material (feces) and returning it to the body. It also absorbs any remaining nutrients. The solid waste material is then passed through the colon to the rectum.
