Nutrition is the most important thing for every person. The body needs a huge amount of chemicals. They regulate its work and are the building material for new cells. Improper nutrition is the cause of most diseases that terrorize modern man. Therefore, information on how digestion works will be useful to everyone, regardless of tastes and preferences. Let's find out where the absorption of nutrients in the human body occurs.
Oral cavity
Useful trace elements from food begin to be absorbed even in the mouth. While eating, saliva is released, which contains enzymes that help break down complex substances. Being in the mouth, the food is saturated with saliva and turns into a more or less homogeneous mass. Unfortunately, it is in the oral cavity for a short period of time, therefore, the intake of nutrients at this stage is insignificant. To change this annoying trend, you need to chew food for a long time and carefully. Everyone knows this, but almost no one follows this simple rule.
Since nutrients hardly enter the blood from the oral cavity, is this stage of digestion useless? In no case! The saliva, which is saturated with food, is actively involved in the digestive processes that take place in the stomach. Therefore, do not underestimate the importance of the digestive transformations that occur in the mouth.
Stomach
One of the places where nutrients enter the bloodstream is the stomach. Chopped and saliva-soaked food passes through the esophagus and ends up in this organ, where the next stage of the digestive process awaits it. The stomach produces hydrochloric acid, mucus and enzymes. It is in its depths that the main amount of water is absorbed, as well as minerals and amino acids that have already broken down. Some glucose is also absorbed in the stomach.
Alcohol, as many have seen from their own experience, is also absorbed here. Therefore, if you take it on an empty stomach, then the effect occurs quickly, which often leads to disastrous consequences. If the consumption of alcoholic beverages takes place with food intake, the poisonous substance is absorbed more slowly, and the effect is not so swift and merciless.
Small intestine
The main place where nutrients are absorbed into the bloodstream is the intestines. It is he who is the main organ of digestion, in which the most important processes function. In the small intestine, the most intensive and effective absorption of beneficial elements from food occurs. This is due to its structure - the surface of the small intestine is covered with legions of villi, which increases the absorption area hundreds of times. Thanks to this design, the main nutrients enter the bloodstream through the villi of the small intestine. With their reduction, the assimilated elements enter the bloodstream, and during relaxation, the free space is filled with a new portion of substances. Also, villi contribute to the mechanical movement of food through the intestines.
The small intestine is an essential part of the digestive system, where nutrients are absorbed into the blood and lymph. Therefore, you need to take care of his health, fight parasites. Maintaining this essential organ in perfect condition will help a healthy diet. It is advisable to exclude from the diet fast food and all kinds of developments in the chemical industry, from which supermarket shelves break. Eat more vegetables, as plant fiber cleanses the intestines like a ruff, as a result of which more fibers can reach the coveted food.
Colon
In the colon passes the final stage of the digestive chain. Water residues, some monomers and vitamins, as well as salts, are absorbed here. If the previous stages of food digestion went well, then a mass that is almost devoid of nutrients enters the large intestine. Therefore, after the final stage of assimilation, stool will be formed from the remnants of food, which will proceed to the exit.
The intestines are not only the place where nutrients enter the bloodstream. In fact, it is he who is responsible for the human immunity. In addition, the microflora that lives in the intestines produce B vitamins, vitamin K, as well as some amino acids, many of which are recognized as essential. The development of beneficial microflora and the destruction of pathogenic - an important task in maintaining health.
Microflora
The beneficial bacteria that inhabit the intestines are vital inhabitants of our body. They are a key component of the immune system, without which the normal functioning of defense mechanisms is unthinkable. Also, many of the essential substances involved in the construction of new cells are produced precisely thanks to the microorganisms that inhabit our intestines.
It would be logical to take care of the precious microflora, to protect and feed it in every way. But most people do exactly the opposite, putting in a lot of effort to destroy beneficial microorganisms. Moreover, they not only kill beneficial bacteria, but also create conditions in the intestine that are ideal for the emergence of pathogenic microflora. This state of affairs is caused by the fact that modern man eats non-food products. For example, convenience foods, fast foods, all kinds of snacks, generously sprinkled with chemicals.
Bowel contamination
The intestine is the place where the absorption of nutrients by the villi occurs. When its walls are contaminated with food debris, stones or parasites, access to these formations ceases. Because of this, the absorption capacity of some sections of the intestine decreases, and sometimes, with a completely unhealthy lifestyle, almost the entire intestinal tract becomes clogged. This phenomenon has led to the fact that modern people need so much food. After all, if the intestine is almost not involved in digestion, then most of the nutrients will not be absorbed. The body will have to be content with what it has time to get in the mouth and stomach. Accordingly, it is necessary to absorb inadequate masses of food in order to get a daily intake of nutrients.
In order to keep clean the place where nutrients enter the bloodstream, you need to eat healthy foods, not to consume incompatible foods at one time . For example, you should not combine protein food with carbohydrate, dairy products are better to eat separately from everything, like fruits. It will also not be superfluous to introduce more vegetables into your diet. The fibers of which they are made will pass through the intestines, removing impurities accumulated on its walls.
What happens to nutrients?
After getting into the blood, beneficial substances and trace elements begin to spread into the cells of the tissues that make up our body. There they take part in metabolism, or metabolism. Metabolic processes are incredibly important for maintaining our vital functions, since it is thanks to them that the necessary proteins, amino acids and other bricks are formed from which the human body is built. Building materials go a long way from the place where the absorption of nutrients in humans takes place, to every organ, any cell of our body.
A harmonious and harmonious metabolism lays a solid foundation for building a healthy body. The person whose metabolism is in order has good health, a lot of energy and a good mood. If this process is disrupted, then the problems will not take long. This can lead to disturbances in the endocrine system, gout, excess cholesterol, impaired mental development and many other bad things.
The Importance of Digesting
The importance of places where nutrients enter the bloodstream is hard to overestimate. The health of the whole organism depends on their harmonious and harmonious work. If there is a problem with the stomach or intestines, then building materials for cell renewal will cease to flow. And this is fraught with a lot of problems with both physical health and mental.
The task of man is to help these vital processes in all possible ways, or at least not to interfere with them. Eat healthy foods and your life will shine with new colors!
