Historyof (experimental) Physiology • Hippocrates(460 – 370 BC), created an intellectual and philosophicalatmosphere that laid the foundation for use of animals for experimental • Aristoteles(384-322 BC), founder of biology, dissections demonstrated the internal differences among animals. • Erasistratus (304-250 BC) founder of physiology, animal experiments similar to recent experiments. Studied the cerebrum, cerebellum, nerves, and the valves of the heart. • Galen (130-200)dissections of all kinds of animals,what he saw mistakenly applied to the human body.left heart and the arteries contained air, the blood being generated in the liver • Vesalius (1511-1564) founder of modern anatomy, used animals in public anatomical demonstrations during the Renaissance
William Harvey (1578-1657) • the first to implement the scientific method to solve biological problems • complete fall of Galen's system and a revolution in physiology
