Blood flows from your superior and inferior vena cava into the right atrium, through the tricuspid valve into the right ventricle, and is then pumped into your pulmonary system. The oxygenated blood returns from the pulmonary vein into the left atrium, through the bicuspid valve, and into the right ventricle - where it is pumped into the body. The lower chambers of the heart, or the ventricles, are much more muscular because of all the pumping they do. The valves (bicuspid and tricuspid) prevent the blood from going "backwards" so to speak, and returning to the atria while the ventricles are contracting.
Due to VALVES. which doesn't let the blood flow in backwards direction!!
The atrioventricular valves ensure one-way flow of blood through the heart - atria to ventricles.
When the heart chambers are contracting at their maximum force to push blood out of the heart it's called systole.
The heart chambers are called atria and ventricles. Arteries and veins are blood vessels.

Because they pump the blood out of the heart
the left atrium and left ventricle are the heart chambers which pumps blood toward the artery. . . xD
The hearth valves only allow blood to flow one way.
weLL..i dont know.. diS iS so haRd..
the purpose of having 4 chambers is they help pumb blood roung your body. they are very helpful because that means your heart doesnt have do it on its own that's why i know lots about the heart chambers xx
The ventricles are the lower chambers of the heart. The atria are the upper chambers.
Atria receive blood into the heart and ventricles "discharge" it from the heart
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.
Normal heart sounds are caused by the heart beating. This is the process of the heart muscle contracting and relaxing as blood flows through the various chambers.
gorillas have a heart with 4 chambers and a blood system that uses hemoglobin

The lower chambers of the heart have a different function than the upper chambers. The lower chambers pump the blood out of the heart into the body and lungs.
The heart is divided by a partition or septum into two halves. The halves are in turn divided into chambers. The upper two chambers of the heart are called atria and the lower two chambers are called ventricles. The atria receive blood returning to the heart from the body and the ventricles pump blood from the heart to the body. Valves allow blood to flow in one direction between the chambers of the heart.
