What is the way of the digestive system?
The digestive system includes a number of organs that operate in the cooperation of the food breakdown process into molecules that the body either uses or destroys. The path of the digestive system begins at the mouth, where the food is inserted and ends in the rectum where the waste is excluded. Meanwhile, there are different organs, each with their own role plays in the digestive process.
As soon as the food enters the mouth and is chewed, it enters the pharynx, leading to the esophagus. In the path of the digestive system, the esophagus is a tube similar to an organ that acts as a path for food to get into the stomach. The food moves through the esophagus peristalize muscles and is still lubricated by mucus secreted in the esophagus lining. The beginning and end of the esophagus contain the muscles of the sphincter to help the food to enter from the pharynx and get into the stomach. Stomach excludes digestive juices that contain hydrochloric acid that kills bacteria and prepares protein for decomposition of pepsin enzymes. Acid in digestive juices is so strong that the stomach must also produce mucus that prevents the aby was spent. Once the food is partially cleaved, it continues along the way of the digestive system to the small intestine.
The small intestine consists of three sections: duodenum, jejunum and ileum. The small intestine measures a stunning diameter of about six meters (19.6 feet) and is a place where most enzymatic digestion occurs. Organs, such as the liver, pancreas and bile bladder, eliminate chemicals into the small intestine, which also help the body spend carbohydrates and fats. When the food is ready to leave the small intestine and enter the large intestine, it passes through the ileocecal valve.
The main intestine, also called the large intestine, plays a role in digestion by reabsorbing water and helps in the final absorption of nutrients. As soon as large intestines are reached, the stomach content that has not been digested, along with the food molecules that have not used, will fall away. This waste is known as fecal matter and is stored in the rectum, which is essentially the end of the thickintestines. The waste is then excluded through the rectum during defecation, the physical process controlled by involuntary and voluntary sphincter.
takes an average of 24 to 48 hours for the food to complete the way on the way of the digestive system. Bacteria, viruses and excessive amounts of non -distinctive foods can change the functioning of the digestive system. The imbalance in the production of digestive chemicals can also disrupt digestive functions and may accelerate or slow down the removal of waste.
