Dr. William Harvey

Dr. William Harvey was an English physician from the 17th century who revolutionized medicine by discovering how blood circulates through the body. He showed that the heart pumps blood in a continuous loop through arteries and veins, rather than blood being generated and consumed locally. His work, published in 1628, laid the foundation for modern cardiovascular science, helping us understand how the body functions and how blood is essential for transporting oxygen and nutrients to tissues. Harvey's insights replaced longstanding misconceptions and significantly advanced medical knowledge.
