Blood flow dynamics refers to the movement of blood through the circulatory system, which includes the heart, arteries, veins, and capillaries. This flow is influenced by factors such as blood pressure, vessel diameter, and blood viscosity. Understanding these dynamics helps in assessing how efficiently blood delivers oxygen and nutrients to tissues and removes waste products. The heart acts as a pump, creating pressure that propels blood through the arteries and into smaller vessels. As blood travels, it encounters resistance, particularly in the capillaries, where exchange of gases and nutrients occurs. Proper blood flow is essential for maintaining overall health and preventing conditions like hypertension and atherosclerosis.
