What causes the heart to move?

Is that movement called a beat?

The movement of the heart is primarily caused by the contraction of its muscular walls, specifically the cardiac muscles. The heart has four chambers: two atria and two ventricles. When the heart contracts, the atria push the blood into the ventricles, and then the ventricles forcefully contract, pumping the blood out of the heart and into the circulatory system.

Yes, each contraction of the heart is commonly referred to as a "beat." The heart typically beats in a regular rhythm, with a specific rate that can vary depending on factors like physical activity, emotions, and overall health. The rhythmic beating of the heart is crucial for its function in circulating blood throughout the body, supplying oxygen and nutrients to all the tissues and organs.
