In what organs is the blood oxygenated? The answer to this question is far from everyone knows. However, absolutely everyone knows that a significant decrease in the level of this gas in human blood is fraught with various diseases of blood vessels, the respiratory system and the heart muscle.
In what organs is the blood oxygenated?
To answer this question, we must first recall the school topic on the anatomy of "The Big Circle of Blood Circulation." After all, it is during this process that the tissues of the body are saturated with all the necessary substances and oxygen. And this happens as follows: from the left ventricle of the heart muscle, arterial blood gradually flows through the arteries to all organs of the body. As a result of a large circle, a peculiar gas exchange occurs in the capillaries. In other words, oxygen from the blood passes into the tissues, and carbon dioxide, on the contrary, enters from the tissues into the blood. In this case, the red corpuscles become venous and through the vena cava enter the right atrium, and after that into the right ventricle.
Blood saturation with oxygen occurs in the lungs. Almost every student knows about this. By the way, this element is transferred to all internal organs and tissues, not only with the help of our natural pump - the heart, but thanks to special carrier proteins that are found in red bodies or the so-called red blood cells. In medicine, they are called hemoglobin. It is he who shows the degree and level of blood oxygenation.
The norm of oxygen in the blood
In what organs the blood is saturated with oxygen, we found out. However, the next question immediately arises as to what is its norm. It is worth noting that in the normal state almost all hemoglobin binds to oxygen. Moreover, the saturation index itself varies from 96% to 99%. If this level decreases and becomes less than 95%, then a person has severe forms of diseases of the vessels, respiratory system and heart muscle. In addition, with severe anemia (that is, with a significant decrease in hemoglobin level), the patient may notice other changes in the body (for example, weakness, deterioration of the condition of nails, skin, etc.).
If the patient has chronic diseases of the lungs and heart, then such a deviation indicates an exacerbation of the disease. In this situation, you should immediately contact a specialist. If the saturation of blood with oxygen slows down against the background of pneumonia, flu, colds and other acute respiratory infections, this indicates a rather severe course of the disease.
False Understatement
About which organs the blood is saturated with oxygen, we talked a little higher. Now it should be noted that during the medical examination, there are several factors that often lead to a false understatement of the normal level of red bodies. Therefore, for the correct diagnosis, it is extremely important to conduct several laboratory measurements in a row.
