The cardiovascular, actually, is located in the guts of the chest, behind the sternum (or the breastbone).
However, a part of it really is slightly offset Location of the heart , as you can figure out from the picture previously mentioned. For understanding this, I think prerequisite knowledge of the heart's basic anatomy is required.
Okay, first of all, I would need to refute Andrew's things vis-a-vis the evolutionary explanation and the sternum giving resistance.
There is absolutely no reason why the center should be an improved place for the heart to be compared to the most suitable or the left sides of the upper body. When our body was evolving, mother nature had to fit intricate organs in the most effective of methods in the very small space of a body. Thus, our bodies are filled with small asymmetries. Some issues had to be devote the centre, some plain items in the left and some things in the proper. The heart is simply at the heart because there will be lungs on the either area and therefore, there is no space remaining on the sides in the thoracic cavity.
Regarding the real point you raised about the sternum, Andrew, the heart can be enclosed in a double walled sac called pericardium. The pericardium's primary functions are to safeguard the cardiovascular system and anchor it to the structures around it, to lessen friction while it beats and to protect it from overdilating (or overexpanding). So there is no relevant dilemma of the heart pushing against the sternum anytime. The soreness which would produce if your bare cardiovascular pushed against the sternum would be unbearable.
The movement is bound by the pericardium of the heart. The sternum doesn't.
Now, to learn why the cardiovascular is slightly offset to the left, one must know about the essential functioning of the cardiovascular and how circulation is definitely brought about in our body.
The human heart has 4 chambers, namely the Left Atrium (LA), the Left Ventricle (LV), the proper Atrium (RA) and the proper ventricle (RV). The atria are the getting chambers and the ventricles will be the discharging chambers.
In mammals, the function of the right side of the heart is to gather de-oxygenated blood, in the proper atrium, from your body which, via the proper ventricle, is then pumped to the lungs for oxygenation. The left side collects oxygenated bloodstream from the lungs into the left
