Topic Summary: Harvey and the Circulation of Blood (1628)
Key Terms
- Circulation: Blood travels in a continuous loop, pumped by the heart — Harvey's 1628 discovery
- Valves: One-way gates in veins showing blood flows only towards the heart
- Capillaries: Tiny vessels connecting arteries to veins — predicted by Harvey, found by Malpighi (1661)
- De Motu Cordis: Harvey's 1628 publication — "On the Motion of the Heart"
- Galen's theory: Blood made in liver, consumed by organs — disproved by Harvey's calculation
Key Dates
- 1578: Harvey born (trained at Padua — Vesalius's university)
- 1628: De Motu Cordis published — circulation proved
- 1657: Harvey dies — theory not yet fully accepted
- 1661: Malpighi discovers capillaries using improved microscope
- c.1700: Harvey's theory of circulation finally widely accepted
Key People
- William Harvey (1578-1657): Proved blood circulates; used calculation, dissection, experiments
- Marcello Malpighi (1628-1694): Discovered capillaries (1661) — completed Harvey's theory
- Vesalius: Harvey trained in his tradition at Padua — direct observation over ancient texts
Must-Know Facts
- Harvey calculated heart pumps ~260 litres/hour — liver could never produce that much
- Valves in veins only allow blood to flow one way (towards heart) — proved circulation
- Harvey trained at Padua — built on Vesalius's culture of direct observation
- No immediate treatment benefit — doctors still bled patients after 1628
- DCEP: Dissection, Calculation, Experiments, Publication — Harvey's four methods
- Missing capillaries: Harvey predicted them but couldn't see them — Malpighi completed the picture in 1661
- Practical legacy: foundation for blood transfusions — but only possible much later
Cross-Topic Links
- → Topic 36 (Renaissance): Harvey trained at Padua — the same university where Vesalius worked — showing how the Renaissance culture of observation and experiment directly enabled Harvey's discoveries.
- → Topic 41 (Surgery Revolution): Harvey's understanding of circulation was the theoretical foundation for safe blood transfusions; Landsteiner's 1901 blood group discovery finally made that practical benefit real.
- → Topic 33 (Medieval Ideas): Harvey demolished Galen's theory that blood was made in the liver and consumed — completing the Renaissance challenge to medieval authority that Vesalius had begun.
- → Topic 40 (Germ Theory): Like germ theory later, Harvey's discovery changed medical understanding without immediately changing treatments — a recurring pattern in medical history.
- → Topic 47 (War and Medicine): Blood transfusion — made possible by Harvey's foundational understanding of circulation — was developed into a practical technique under the pressure of WW1 casualties.
