Answer:

The correct answer is option a) "preload".

Explanation:

In cardiology, the concept of preload refers to the initial stretching of the cardiomyocytes to its greatest dimensions prior to contraction. This first stretching is achieved by a difference of pressure between the ventricles, which happens by the pump of an increased amount of blood in one of the ventricles. The result is that one ventricle has a greater dimension than the other, but the blood arrives to the other and causes to increase its stroke volume and match that of the other.
