The study of the design and function of the human body was a lifelong interest for Leonardo da Vinci. From about 1507 onwards, he devoted a lot of his thinking and creativity towards the heart. While he started with studying the hearts of pigs and oxen, he was able to gain access to human bodies later in his life. His understanding of the design and function of the human heart was extraordinary.
Da Vinci used his vast knowledge of engineering, fluids, and levers to help understand the function of the heart. No one had done this before, so his perspectives on the heart were revolutionary. He also developed an understanding of heart valves and the flow of blood through them. Leonardo also understood that the heart was a muscle, and that it did not, as most thought at the time, warm the blood. Many of his astute observations and conclusions about the heart are still true today. His work on the heart is simply astounding.
