Before entering fully into the establishment of the meaning of the term atrium, we are going to know its etymological origin. In this case, we can say that it is a word that derives from Latin. Specifically, it comes from “auricula”, which can be translated as “little ear” and which is made up of two clearly differentiated parts:
-The noun “auris”, which is synonymous with “ear”.
-The suffix “-cula”, which is used as a diminutive.

The term atrium It can be used in different areas. In the field of anatomy, the atrium is called the cavity that exists in the heart, where the blood comes from the blood vessels.

Precisely if we take into account their etymological origin, we can say that these cavities of the aforementioned heart are thus called because they have the appearance of an ear.

AtriumAlso known as courtyards, the atria in the heart of the human being They are two cavities that are located in the upper sector of the organ, above the ventricles.

Carbooxygenated blood, after traveling through the body, enters the right atrium of the heart through the vena cavae. Through the tricuspid valve, the blood It passes from the right atrium to the right ventricle and then, through the pulmonary valve, to the so-called pulmonary artery. In this step, the lungs oxygenate the blood and the fluid, through the pulmonary veins, returns to the heart.

The oxygenated blood then enters the left atrium and, via the mitral valve, it passes to the left ventricle. Finally, the aorta artery is responsible for carrying blood to the rest of the organism.

Within the set of diseases, pathology, conditions or health problems of all kinds that can affect the atria is what is called atrial fibrillation. This comes to refer to a very common chronic arrhythmia that is characterized by being composed of disorganized atrial beats.

This situation is dangerous in that it increases the risk of suffering a stroke. It should also be borne in mind that those who are most likely to suffer from fibrillation are people with these characteristics:
-They have problems with their weight, either because they are overweight or obese.
-They suffer from type 2 diabetes.
-They have what is known as high blood pressure.
-No less relevant is that those who have health problems related to the thyroid also have risks.
-It should not be overlooked that, in the same way, those who have some type of heart disease or those who have an injury in what are the heart valves are more likely to suffer it.

It should be noted that the number of atria in the heart depends on the species. Have been found mollusksFor example, they have four atria, twice the number in the human heart. Therefore, it cannot be said that the heart, on a general level, has a X number of atria, since the data is directly linked to the species.

For the botany, the atrium is the extension of the lower region of the limbo, the widest part of the leaves. It is a foliaceous-type lobe, which is located next to the petiole.
