Before entering to define the concept of aorta, it is necessary that we
determine its etymological origin. Specifically, this is found in the Greek and
more exactly in the word άορΤή, which in turn comes from the term άείρειν which
could be translated as “to raise”.
It is defined as an aorta to the artery that
originates in the ventricle located in the left region of the
heart muscle and that forms an arch and extends towards the abdomen
area. There, at the level of the fourth lumbar vertebra, it has a bifurcation
that extends into two smaller arteries, which are called primitive
And that without forgetting that it is also necessary to emphasize that said
artery is the largest of all those that exist in the human body.
Since the aorta constitutes the starting point of the rest of the arteries
that are part of the circulatory system (with the exception of
the pulmonary arteries, which leave the right
ventricle), it is considered, on a medical level, as the most
important artery in the human organism. Its function is to allow the
transfer and guarantee the distribution of oxygen-rich blood to
the other arteries.
the aorta is an artery with elastic characteristics that
has flexibility and can be extended. When the
left ventricle contracts to supply blood to the aorta (a process known as systole),
an expansion occurs in it, which gives it the potential energy to help maintain
blood pressure when the artery ends up contracting passively (diastole).
There are several diseases or pathologies that can affect said artery such as
coarctation, which can be defined as a congenital type defect that is suffered
in the heart and which means that it is affected by a narrowing. This means,
among many other things, that the person in question who suffers from it is more
likely to develop an infection in the aorta.
Likewise, mention should also be made of what is known as an aneurysm. This
pathology is totally contrary to the previous one and is that it consists of the
abnormal widening of the artery in question. In this case, a very specific one
that can lead to a break in the wall of the wall and therefore the patient's
life is very seriously endangered.
Among the different recognizable segments in this artery are the so-called ascending
aorta (a portion that is located between the heart and the arch, where
the coronary arteries that carry blood to the myocardium originate), the aortic arch or arch (whose
appearance it resembles a letter U but inverted and stands out for marking the
beginning of the brachiocephalic trunk, the primitive carotid and the left
subclavian) and the descending aorta (which extends from the
aortic arch and ends in the division of the iliac arteries). The thoracic
aorta may be mentioned as the half of the descending aorta above the
diaphragm and the abdominal aorta. as the part of the
descending aorta that lies below the diaphragm and reaches the bifurcation of
In addition to all the aforementioned, we can add that aorta is a word that
is part of a broader term: aortic arch. With it, the arch that said artery forms
from its birth to reaching the abdomen is defined.
