With etymological origin in the Latin word atrium, atrium is a concept that can be used to name the discovered sector which is in the entrance of certain buildings.
The atrium, in this sense, is a kind of patio with porches in its surroundings . In the ancient Roman temples, all people they could access the atrium, while only the faithful had the entrance allowed inside the building.
Some temples used the atrium as cemetery . The courts could also help to mark a delimitation of the sacred space, separating it from the rest of the surface .
According to the dictionary of the Royal Spanish Academy (RAE ), atrium can be used as a synonym for hallway (a roofed section that allows the entrance to a house, located next to the door).
In the old Roman houses we have to expose that there was what was known as the atrium, which was the first courtyard that existed just after the lobby. There was the circumstance that in that place it was where the cistern was in charge of collecting the rainwater and called impluvium.
Within art and architecture, in particular, we can emphasize that the atriums become essential elements of numerous constructions. Specifically, in Spain they became fundamental spaces in the Castilian Romanesque churches. Good examples of this are those who have the Church of San Esteban de Segovia or the Church of San Lorenzo, also in the city of Segovia.
And it is that in those temples the atrium was given value as an area in which to bring together what were the open councils.
However, there are many examples of temples endowed with these courts, such as the Church of San Miguel in San Esteban de Gormaz, the Church of San Vicente in the city of Ávila, the Church of San Miguel in Cuéllar or the Cathedral from Jaca
The atriums of constructions such as St Mary of Yatton in England, the Cathedral of Tuy, that of the Glory of Santiago de Compostela stand out worldwide ...
We cannot overlook either that "Atrium" is what is called the magazine of Art History that belongs to the Pablo de Olavide University of Seville.
In the field of medicine , the idea of atrium may appear as a synonym for atrium . The atria are two cavities that are located in the upper part of the heart, above the ventricles.
To the right atrium the carboxygenated blood arrives that, after crossing the organism, accesses the heart through the vena cavas. The tricuspid valve allows blood to pass to the right ventricle and then, through the pulmonary valve, to the pulmonary artery. The blood It is then oxygenated in the lungs and returns to the heart thanks to the pulmonary veins.
To the left atrium , therefore, comes the already oxygenated blood that comes from the lungs . This atrium, through the mitral valve, drives blood to the left ventricle, which takes it to the rest of the body via the aortic artery.
