Details of the organs in which blood is saturated with oxygen

In what organs is the blood saturated with oxygen? Not everyone knows the answer to this question. However, everyone knows that a significant decrease in the level of this gas in the blood of a person is fraught with various diseases of blood vessels, the respiratory system and the heart muscle.

In what organs is the blood saturated with oxygen?

To answer this question, you should first recall the school topic on the anatomy "The Great Circle of the Circulation". It is during this process that the tissues of the body are saturated with all the necessary substances and oxygen. And it happens this way: from the left ventricle of the heart muscle, the arterial blood gradually flows along the arteries to all organs of the body. As a result of a large circle in the capillaries is a kind of gas exchange. In other words, oxygen from the blood passes into the tissues, and carbon dioxide, on the contrary, comes from the tissues into the blood. At the same time red corpuscles become venous and go through the hollow veins to the right atrium, and then to the right ventricle.

Saturation of blood with oxygen occurs in the lungs. Almost every schoolboy 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 contained in red bodies or so-called erythrocytes. In medicine, they are commonly called hemoglobin. It is he who shows the degree and level of oxygen saturation of the blood.

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. At the same time, the saturation index itself ranges from 96% to 99%. If this level decreases and becomes less than 95%, then a person has severe forms of vascular, respiratory and cardiac muscle diseases. In addition, with severe anemia (that is, with a significant decrease in hemoglobin), the patient may notice other changes in the body (for example, weakness, deterioration of the nails, skin, etc.).

If the patient has chronic lung and heart disease, then this deviation indicates an exacerbation of the disease. In this situation, you should immediately contact a specialist. In the event that oxygen saturation slows down against pneumonia, influenza, colds and other acute respiratory infections, this indicates a rather severe course of the disease.

A false underestimation of the oxygen level

About that, in what organs the blood is saturated with oxygen, we have told hardly above. 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 corpuscles. Therefore, in order to correctly diagnose it is extremely important to conduct several laboratory measurements in a row.
