Answer:
When comparing the thickness of the heart's ventricles, the left one is thicker than the right one, because it must generate more pressure to pump blood throughout the body.
Step-by-step explanation:
In the human heart, the right ventricle is in charge of pumping the blood to the lungs —initiating the minor circuit of the circulation— while the left ventricle is in charge of pumping the blood to the whole body.
To fulfill its function, each ventricle has a specific thickness in its walls, the left one being thicker than the right one.
- The right ventricle is a chamber that handles more volume than pressure, and its walls are thinner because it does not require much pressure to pump the blood to the lungs.
- The left ventricle has a thicker muscular wall because it is a chamber that must generate a high pumping pressure, so its contraction force must be greater.
The structure of the myocardium in the heart is what allows each chamber to fulfill its function adequately.
