What word best describes the beating of heart and circulation blood?

The word that best describes the beating of the heart and circulation of blood is "circulation." Circulation refers to the continuous movement of blood throughout the body, driven by the pumping action of the heart. The heart contracts and relaxes, propelling blood through a network of blood vessels known as the circulatory system. This process ensures that oxygen-rich blood reaches all tissues and organs in the body, while removing waste products such as carbon dioxide. The circulatory system plays a vital role in maintaining homeostasis and supporting the body's overall function.
