The Motion of the Heart and Blood (work)

The motion of the heart and blood involves the heart contracting to pump blood throughout the body, driven by electrical signals that coordinate each heartbeat. When the heart muscle contracts, it pushes blood into the arteries; when it relaxes, it fills with blood from the veins. The rhythmic process maintains blood flow, delivering oxygen and nutrients while removing waste. The entire system relies on pressure differences and the elasticity of blood vessels, creating a continuous, efficient circulation essential for sustaining life and supporting bodily functions.
