Their autorhythmicity means that they move at a certain rate and follow a particular path. Here are a few interesting facts about the heart. We can learn more about the heart's function and how it affects the body. The heart has four chambers. The two upper chambers are called atria, while the two lower chambers are known as ventricles. Each chamber is separated by a muscular wall, called a septum. The left chamber pumps blood most powerfully, which is why you feel the heartbeat more on the left side of the chest. The right side contains the opposite chambers. When one side is pumping, the other chambers are relaxed.
