Due to what the movement of blood through the vessels is continuous?

The movement of blood through the vessels is provided due to the work of the heart. The heart, with the help of weak electrical impulses, is able to beat rhythmically. Due to the contraction, as well as the work of the valves, blood is pushed out of the organ and begins to move through the vessels. This happens very quickly. A complete circulation of blood through the body takes place in 27 heartbeats. This takes about half a minute. Although the heart beats rhythmically, due to the closed circulatory system, blood flows continuously and pulsation can be clearly seen in the arteries.
