Our body is composed of several cells, tissues and organs that together form some systems that perform essential functions for our survival. One of them is the digestive system, which acts on the disintegration and absorption of nutrients from the foods we eat daily.
Read on to learn more about how this system works and what are the fundamental steps for this process to occur in our body.
What is digestion and how important is it for our organism?
Food is a source of numerous nutrients, which are only absorbed and used by the body due to the digestion process.
Digestion is the name given to the process of physical and chemical disintegration of organic foods so that they are absorbed by our body, ensuring the proper functioning of the whole body.
This process is done throughout the digestive system, which starts at the mouth during chewing, passing through the stomach, which causes a greater breakdown of food particles, going to the small intestine, where complete absorption of nutrients occurs.
In all, the bodies that make up this system are:
Mouth: considered the gateway, the mouth is formed by the lips, teeth (essential for chewing) and tongue (important for the perception of flavors and swallowing). It is in the mouth that the first breakdown of food occurs, so that they are swallowed and move on to the next stage of digestion.
Pharynx: common to the digestive and respiratory system, the pharynx is a mucosa through which the bolus (name given to food after chewing) passes to reach the esophagus and, soon after, to the stomach. This stage is called swallowing (swallowing).
Esophagus: tube that connects the pharynx and stomach, the esophagus has the function of pushing, through movements called peristaltics, the food bolus so that it accesses the stomach.
Stomach: located below the diaphragm, the stomach is responsible for the chemical digestion of the bolus, since within this organ an acidic substance (gastric juice) is released which breaks down the bolus into particles.
Small intestine: 6 meters long and divided into 3 portions (duodenum, jejunum and ileum), the small intestine is the longest part of the digestive system. It has the function of completely absorbing the nutrients of the chyme (name of the bolus after the action of gastric juice in the stomach).
Large intestine: representing the final stage of digestion, the large intestine (divided into cecum, colon, rectum and anus) measures around 15 cm, and has the function of absorbing water from the chyme, transforming it into fecal cake, which will be eliminated by the anus.
If any of these organs does not function properly, chances are that the digestion process will not operate properly, compromising the absorption of nutrients and elimination of waste (feces).
Therefore, it is important to consult a doctor when you notice frequent symptoms such as loss of appetite, heartburn , diarrhea , constipation , weight loss or weight gain quickly, as well as tiredness and other symptoms.
