What is the structure of the digestive system?
When a person eats food, the body must turn this meal into molecules chains that can be converted into energy and raw nutrients. The human digestive system controls the distribution of nutrients and energy in the body by undergoing chemical reactions when it passes through the digestive tract. The structure of the digestive system, also known as an alimentary channel, allows different organs to gradually decompose and process food. In addition to the mouth and esophagus, there are three main organs and many smaller organs in the digestive system. The digestion process begins in the mouth, with saliva moisturizing and breaking down food into masterable pieces.
The stomach is the first part of the structure of the digestive system, consisting of a muscular hollow bag, located just below the membrane and a chest basket. It is separated from the esophagus and small intestine by the esophageal and pyloric sphincter sphincter. The structural system requires that the food to disintegrate before switching to the rest of the digestive channel; The mucus film covers the lining of the stomach to protect the walls of the stomach from the hydrochloric acid that liesMala food. The food remains in the stomach until it reaches physical digestion to make more suitable for nutrient extraction in the small intestine.
after the food in the stomach falls apart, it passes into the small intestine immediately below the structure of the digestive system; The small intestine is an average of 20 feet (about six meters) on average for adults. The small intestine performs most of the work of chemical digestion through enzymes secreted by the pancreas. The proteins disintegrate into amino acids, fats fall into glycerol and carbohydrates disintegrate into glucose and other sugars. The inner wall of the small intestine contains finger fingers called Villi, which catches food molecules and passes it to external capillaries and then into larger blood vessels.
The small intestine connects to the large intestine. The main intestine is the last main part of the digestive system structure and is responsible for the absorption of excess water, the conversion of the solidDad on the stool and its excretion. Bacteria based in the small intestine, known as intestinal flora, absorb solid material remaining after all nutrients and energies have been extracted from food and drink. Travel waste usually takes the day to travel through the large intestine.
