The movement of blood through the vessels is referred to as circulation, which is a vital process in the body. Circulation is primarily driven by the pumping action of the heart, which creates pressure that pushes blood through arteries, capillaries, and veins. This continuous flow of blood ensures the delivery of oxygen and nutrients to cells and the removal of waste products. Understanding circulation is essential for CNAs, as they often monitor and assist with patients' cardiovascular health.

The chain of command outlines the hierarchy in healthcare settings and the line of authority but is unrelated to the biological mechanisms that facilitate circulation.
