physics of blood dynamics

Blood dynamics involve the movement of blood through the body's vessels, driven primarily by the heart's pumping action. When the heart contracts, it creates pressure that pushes blood into arteries, which branch into smaller arterioles and capillaries, allowing oxygen and nutrients to reach tissues. The blood then collects into veins, returning to the heart. This flow is influenced by vessel elasticity, diameter, and blood pressure, with factors like resistance and viscosity affecting how easily blood moves. Overall, blood dynamics balance pressure, flow rate, and vessel health to ensure efficient circulation throughout the body.
