stomach, mouth, intestines. So simple
There are 3 parts to the small intestine: the duodenum, jejunum and ilium(in that order after the stomach). The duodenum is the first part of the small intestines. It is relatively short (12 inches) and starts at the pyloric sphincter of the stomach, and connects it to the jejunum.
I know that it takes about 8 hours to get through both the stomach and the small intestine. And most digestion occurs in the small intestine. So, probably about 2-3 hours. Remember, the stomach only has the enzyme to digest proteins, so why on earth would a lot of digestion occur in it?
The small intestines is the longest organ in the alimentary canal.
The acidic environment of the stomach helps break down foodstuffs that was ingested and also kills potential bacteria. The alkaline environment of the intestines facilitates the absorption of nutrients.
Food stays in the small intestine about 3-5 hours
The small intestines has a diameter of about 3 cm, and can vary greatly in length. An average adult can have a small intestine that is anywhere from 15 to 32 feet in length. The small intestine is comprised of three parts: duodenum, jejunum, and ileum.
The stomach looks like a fist lying sideways with a wrist (e.g. make a duck with your hand, as if making a shadow puppet on the wall, except the area of your fingers is rounder). The "wrist" side, close to the center of the body, is where the stomach empties toward the left side into the small intestines.
When stomach is empty, leaves immediately and goes into intestines. http://forums.randi.org/showthread.php?t=132551 Keith S. :{)>
Food typically takes around 3-5 hours to travel through the small intestines. The exact time can vary depending on factors such as the type of food consumed and individual digestion rate.
