Among all the sections of the digestive tract, the small and large intestine have the largest ranges of measured values.

Why are measurements of the small intestine more accurate?

Besides this natural variability between individuals, there is also a high uncertainty in measurements. This is due to the difficulty of accessing these organs, hidden in our bodies. For instance, measurements of the small intestine during a surgical operation, such as a laparotomy, show a higher length than other techniques not involving the manipulation of the gut. Measurements of the large intestine after death tend to be higher than in vivo measurements. Other techniques more accurate include intubation, and especially radiography which does not disturb mechanically the organs 3.

Microorganisms also are kept at bay by an extensive immune system comprising the gut-associated lymphoid tissue (GALT)

Upon dissection, the duodenum may appear to be a unified organ, but it is divided into four segments based upon function, location, and internal anatomy. The four segments of the duodenum are as follows (starting at the stomach, and moving toward the jejunum): bulb, descending, horizontal, and ascending.

How does my digestive system work?

Each part of your digestive system helps to move food and liquid through your GI tract, break food and liquid into smaller parts, or both. Once foods are broken into small enough parts, your body can absorb and move the nutrients to where they are needed. Your large intestine absorbs water, and the waste products of digestion become stool. Nerves and hormones help control the digestive process.

How does food move through my GI tract?

Food moves through your GI tract by a process called peristalsis. The large, hollow organs of your GI tract contain a layer of muscle that enables their walls to move.

The muscle behind the food contracts and squeezes the food forward, while the muscle in front of the food relaxes to allow the food to move.
