ventricles
The left venricular chamber of the heart is responsible for pumping the blood throughout the body
the left ventricle.. :)
it just happens OK?
left atrium
The pumping action involves the heart's chamber contracting and relaxing. The heart beat is one cycle of the heart going through this contraction and relaxation while pumping blood.
there are two chambers with a s shaped cosisting of the type of body plan they have
The left ventricle is the largest chamber in the heart. It is responsible for pumping oxygenated blood to the rest of the body and has thicker muscular walls compared to the other chambers to withstand the pressure needed for systemic circulation.
Sudden cardiac death is usually caused by ventricular fibrillation (the lower chamber of the heart quivers instead of pumping in an organized rhythm).
The left ventricle is responsible for pumping oxygenated blood out to the entire body, whereas the right ventricle is only responsible for sending deoxygenated blood to the lungs to become oxygenated. Therefore, the left ventricle is more powerful and tends to be slightly larger.
The thin-walled priming chamber pump of the heart. Each of the two atria lies above the ventricle, separated by a one-way atrioventricular valve. The function of the atrium is to force the last bit of blood into the main pumping chamber (ventricle) before the power stroke to increase the efficiency of pumping.
The heart has 4 chambers. The "collecting chamber of the heart", or the atria , is the two chambers that are located above the other two chambers. It carries the responsibility in helping to pump the blood out of the chambers and making sure no blood pumps back in.
