🧠 How Did Harvey Prove It?
Dissection — Studied hearts of over 40 species of animals. Observed valves in veins only allowed blood to flow one way.
Calculation — Measured the heart pumped about 60mL per beat. At 72 beats/minute = 260 litres per hour. The liver couldn't make that much!
Experiments — Tied off veins to show blood built up below the tie (proving blood moved towards heart). Used cold-blooded animals (slower heartbeat) to observe pumping.
Publication — On the Motion of the Heart (1628) explained his findings with detailed diagrams.
