Do the differences in the thickness of the heart chamber walls relate to functional differences?
Left Ventricle: Very very thick wall, has to pump blood at very high pressure to the whole body.
Right Ventricle: Thickish wall, has to pump blood at high pressure to the lungs.
Right atrium/left atrium: Thin walls, only has to pump blood to ventricles.
Remember the heart chamber wall is made of muscle so think about it like the further the distance the blood needs to travel the thicker the muscle needed.
The walls of the ventricles are thicker because they need to work more to push blood through them to either the lungs or systemically whereas the atria only need to move the blood into the ventricles.
A heart attack
The heart is a single organ, but it functions as a double pump sending oxygen-depleted blood to the lungs to pick-up oxygen and unload carbon dioxide, while simultaneously sending oxygen-loaded blood coming from the lungs to cells throughout the body. The heart's right ventricle pumps blood to the lungs, while the left ventricle pumps the oxygenated blood to the body cells.
