Where do nutrients enter the bloodstream of a person?

Food is the most important thing for every person. The body needs a lot of chemicals. They regulate its work and are the building material for new cells. Malnutrition is the cause of most diseases that terrorize modern humans. 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 takes place in the human body.

Oral cavity

Useful micronutrients from food begin to be absorbed even in the mouth. During the reception of food saliva is released, which contains enzymes that help to break down complex substances. Being in the mouth, the food becomes impregnated with saliva and turns into a more or less homogeneous mass. Unfortunately, it is in the oral cavity for a short time, so the intake of nutrients at this stage is negligible. To change this unfortunate tendency, you need to chew food for a long time and thoroughly. Everybody knows about this, but practically no one follows this simple rule.

where nutrients enter the bloodstream

Once the nutrients from the oral cavity almost do not enter the blood, then this stage of digestion is useless? In no case! Saliva, which is saturated with food, takes an active part in the digestion processes that take place in the stomach. Therefore, do not underestimate the importance of digestive transformations that occur in the mouth.


One of the places where nutrients enter the blood is the stomach. Chopped and salted food passes through the esophagus and is in this organ, where it is waiting for the next stage of the digestive process. The stomach produces hydrochloric acid, mucus and enzymes. It is in its depths absorbed the main amount of water, as well as minerals and amino acids, which have already split. Some amount of glucose is also absorbed in the stomach.

nutrients enter the bloodstream through the villi of the small intestine

Alcohol, as many have learned from experience, is also acquired here. Therefore, if you take it to an empty stomach, the effect comes quickly, which often leads to disastrous consequences. If the consumption of alcoholic beverages goes along with the intake of food, then the poisonous substance is more slowly absorbed, and the effect is not so swift and merciless.

Small intestine

The main place where nutrients are absorbed into the blood is the intestine. 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 assimilation of useful elements from food takes place. This he owes his structure - the surface of the small intestine is covered with legions of villi, which increases the absorption area by hundreds of times. Thanks to this design, the main nutrients enter the bloodstream through the villi of the small intestine. With their reduction, the acquired elements enter the bloodstream, and during relaxation, the free space is filled with a new portion of substances. Also villi promote the mechanical movement of food through the intestines.

where the absorption of nutrients into the blood occurs

The small intestine is the most important part of the digestive system, where nutrients are absorbed into the blood and lymph. Therefore, you need to take care of his health, to fight against parasites. To support this important organ in an ideal condition will help a healthy diet. It is desirable to exclude from the diet fast food and all sorts of chemical industry developments, from which the supermarket counters are bursting. Eat more vegetables, as vegetable fiber cleanses the intestines like a ruff, resulting in more villi can get to the cherished food.

Large intestine

In the large intestine passes the final stage of the digestive chain. Here, the remains of water are digested, some monomers and vitamins, and also salts. If the previous stages of assimilation of food went well, then the bulk of the large intestine, almost devoid of nutrients. Therefore, after the final stage of digestion, the feces will be formed from the food residues, which will proceed to the exit.

Intestine is not only a place where nutrients enter the bloodstream. In fact, it is he who is responsible for the immunity of a person. In addition, the microflora that lives in the intestine, produces vitamins B, vitamin K, as well as some amino acids, many of which are recognized as indispensable. The development of useful microflora and the destruction of pathogenic microorganisms is an important task in the preservation of health.


Useful bacteria that inhabit the intestines are the vital inhabitants of our body. They are the key link of the immune system, without which the normal operation of defense mechanisms is unthinkable. Also, many of the irreplaceable substances involved in building new cells are produced precisely by the microorganisms that inhabit our intestines.

It would be logical to take care of the precious microflora, protect it and feed it in every possible way. But most people are directly opposite actions, putting a lot of effort to destroy useful microorganisms. Moreover, they not only kill useful bacteria, but also create conditions in the intestine that are ideally suited for the emergence of pathogenic microflora. This state of affairs is caused by the fact that modern people eat foods that are not food. For example, semi-finished products, fast food, all kinds of snacks, generously sprinkled with chemicals.

Intestinal toxicity

The intestine is the place where nutrients are absorbed by villi. When its walls are contaminated with food remnants, stones or parasites, access to these formations is discontinued. Because of this, the absorption capacity of some areas of the intestine is reduced, and sometimes, in a completely unhealthy way of life, 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 digested. The organism will have to be satisfied with what it will have in the mouth and stomach. Accordingly, it is necessary to absorb inadequate masses of food in order to obtain a daily nutrient norm.

where there is absorption of nutrients into the blood and lymph

To keep a clean place where nutrients enter the blood, you need to eat healthy food, do not eat incompatible foods in one go. For example, do not combine protein foods with carbohydrate, dairy products are better off separately from everything, like fruit. Also, it will not be superfluous to introduce more vegetables into your diet. The fibers from which they are composed will pass through the intestines, removing the impurities accumulated on its walls.

What happens to the nutrients?

After getting into the blood, useful substances and microelements begin to spread to the cells of tissues that make up our body. There they take part in metabolism, or metabolism. Exchange processes are incredibly important for maintaining our life, because it is through them that the necessary proteins, amino acids and other bricks are formed, of which the human body is built. Building materials go a long way from the place where the absorption of nutrients in humans occurs, to every organ, every cell of our body.

The harmonious and harmonious metabolism lays a solid foundation for building a healthy body. That person, whose metabolism is in order, has good health, lots of energy and a good mood. If this process is broken, the problems will not take long to wait. This can lead to disruption in the endocrine system, gout, excess cholesterol, impaired mental development and many other bad things.

The Importance of Assimilating Food

The importance of places where nutrients enter the blood can not be overemphasized. The health of the whole organism depends on their harmonious and harmonious work. If there is a problem with the stomach or the intestines, the building materials for cell renewal will cease to flow. And this is fraught with a lot of problems with both physical health and mental health.

The task of a person is to help these vital processes in any possible way, or at least not to interfere with them. Eat healthy food, and your life will shine with new colors!
