The digestive system and how it works? Digestive system is a series of hollow organs that are connected to each other through a long tube, twisting a continuous tube from the mouth to the anus, inside this tube there is a lining called the mucosa. In the mouth, stomach, and small intestine, the mucosa contains small glands that produce juices that help digest food, two liver organs and the pancreas, produce digestive juices that reach the intestine through small tubes. In addition, parts of other body organs (eg, nerves and blood) play a major role in the digestive system.
The importance of digestion:
When we eat things like bread, meat, and vegetables, they are not in the form that the body can use and use to feed, so its food and drink should be divided into smaller particles of food so that the blood can absorb it and carry it to cells throughout The body represents digestion, the process by which food is divided, as well as dividing the drink into smaller parts so that the body can use it in building, feeding the cells and saving energy.
How to digest food
Digestion involves mixing food, moving it through the digestive system, and the chemical breakdown of large particles of food into smaller molecules. Digestion begins in the mouth. When we chew and swallow, and complete in the small intestine, the chemical process varies somewhat depending on the different types of The food moves through the system, large hollow organs of the digestive system contain muscles that enable their walls to move, the movement of walls in the machine works to push food and liquid, and can also confuse the contents within the device, typical movement of the esophagus, stomach, and Which may be called b Intestinal perforation, doing the work in peristalsis is like an ocean wave moving through the muscles, the muscle of the organ produces narrowing, and then the part is driven by slowly narrowing along the device, these waves of tightening push the food and fluid forward along the entire machine, In the main muscles when swallowing food or liquid, and although we can start swallowing by choice, after swallowing begins, it becomes involuntary and the process becomes controlled by the nerves.
