How does the Digestive System Work? Bodytomy Staff Oct 4, The digestive system is one of the most important organ systems of the human body responsible for digestion process. Read on to know more about this system and how it works. Food digestion is an important metabolic process for survival.
Organs that help with digestion, but are not part of the digestive tract, include the following: Glands in the mouth that make saliva. Parts of other organ systems, like nerves and blood, also play a major role in the digestive process.
How does food move through the digestive system? In a wave-like movement called peristalsis, muscles propel food and liquid along the digestive tract.
In general, there are six steps in the process of moving food and liquid through the digestive system: The first major muscle movement is swallowing food or liquid. The start of swallowing is voluntary, but once it begins, the process becomes involuntary and continues under the control of the nerves.
The esophagus, which connects the throat above with the stomach below, is the first organ into which the swallowed food goes. Where the esophagus and stomach join, there is a ringlike valve that closes the passage between the two organs.
When food nears the closed ring, the surrounding muscles relax and allow the food to pass into the stomach and then it closes again. The food then enters the stomach, which completes three mechanical tasks: First, the stomach stores the swallowed food and liquid, which requires the muscle of the upper part of the stomach to relax and accept large volumes of swallowed material.
Second, the lower part of the stomach mixes up the food, liquid, and digestive juices produced by the stomach by muscle action. Third, the stomach empties the contents into the small intestine. The food is digested in the small intestine and dissolved by the juices from the pancreas, liver and intestine, and the contents of the intestine are mixed and pushed forward to allow further digestion.
Last, the digested nutrients are absorbed through the intestinal walls.
The digestive system is made up of the digestive tract—a series of hollow organs joined in a long, twisting tube from the mouth to the anus—and other organs that . The digestive system is a group of organs working together to convert food into energy and basic nutrients to feed the entire body. Food passes through a long tube inside the body known as the alimentary canal or the gastrointestinal tract (GI tract). The digestive system is a pretty important part of your body.
