William Harvey’s discovery of the circulation of blood greatly advanced the study of physiology. His discovery showed that blood circulates around the body in a closed loop, and not just by gravity. He demonstrated that blood is pumped by the heart and not just by gravity. His discovery helped to explain how blood pressure is regulated, as well as how it is transported around the body and through the lungs.
Harvey’s discovery was vital for understanding how blood clotting is a part of the circulation process, and that blood is composed of plasma and cells.
Harvey’s discovery helped to explain how blood circulates through the body in a rhythmic fashion, which helped to explain its function of transporting nutrients throughout our bodies.
