Most lessons in order to listen to heartbeat, apply a hand or ear to the left side of the chest. Why? Because we are convinced that the heart is located on the left. Where does such information come from? It is especially unknown, but in the accuracy of this fact, the majority is convinced. And where in reality is the heart? Are our beliefs true or are we insubstantly mistaken?
Where are you, heart?
The fact that the heart is located in the chest cavity is a well-known and indisputable fact, a constant, with which you can't argue. However, many, despite the subject of anatomy, we are convinced that the heart is fully placed entirely on the left side of the chest, ignoring that in the chest area there are also other, quite voluminous organs, for example, lungs. What way to the left can fit and the heart, which also has enough impressive sizes, and the left light, and it is more?
The heart is a large organ, compared with a human fist. Considering that in the chest also lungs are located, and they are located symmetrically on the right and left, the heart does not remain anything else, how to sit around in the center in the chest cavity. Of course, his position is not symmetrically there, on the left half of the sternum accounts for its main part, but, nevertheless, to say that the heart is entirely located on the left, it is impossible. Why then then the head of the heart is clearly auditioned from the left side? Here everything is explained by the work of the vessels and valves, which create a characteristic sound - the head of the heart, they are larger on the left side of the organ itself, which is why the knock is clearly heard from the left.
A part in the chest, where the heart is placed, is called a mediastinum, which is again divided into two parts, peculiar floors: upper and lower. And the lower floor is divided into front, medium and rear departments. Why do you need such a clear division? It greatly helps doctors to decide on the impact zone when planning operations, the treatment of cancer with radiation therapy, indirect massage of the heart and other medical manipulations.
In general, know where the heart is located, it is necessary for everyone, since the pains, localized on the left, can not always refer to heartfelt, and pain in the center of the chest can only indicate a heart attack, but may not be recognized from lack of knowledge.
