Heart: the machine of the human body
What is / and both sides
The heart is an organ formed by striated cardiac muscles. It is divided into two sides: the left side (left atrium and left ventricle) and the right side (right atrium and right ventricle).
Operation and functions
From its left side, the heart pumps blood throughout the body, drawing out and distributing substances such as carbon dioxide and oxygen. It is important to know that in addition to this, many other exchanges are performed since through them the balance of our body is maintained.
In addition to the large circulation (cited above), there is also the small circulation, this is so-called because it has a shorter path than the first, however, it is also of as high importance as the one mentioned in the previous paragraph.
In the small circulation, the blood is pumped from the right side of the heart to the lungs, and from within it collects oxygen and releases carbon dioxide. After this he returns to the heart, entering this time into the left atrium. Still on the left side, the heart pumps the blood to the ventricle on the same side, and from there the blood, now filled with oxygen, departs again for the great circulation path.
Even while we are sleeping, the heart does not stop working, while sleeping, it still beats on average 30 times its own weight every minute. However, when we are active it works faster by pumping a much larger volume of blood into the body.
- The branch of science that studies the normal heart and its pathologies is cardiology.
- Heart disease is generically called heart disease.
