The textbook discusses the Scientific Revolution in the context of how print media accelerated scientific discovery by allowing findings to spread rapidly across Europe. Key scientists mentioned include:

• Andreas Vesalius (1514–1564): Published De Humani Corporis Fabrica (1543), which discredited Galen's anatomical views and assembled the first accurate human skeleton from cadaver dissections. The textbook also states that Vesalius “found that the circulation of blood resolved from pumping of the heart” — though this is more fully attributed to Harvey
• William Harvey (1578–1657): The textbook explicitly states Harvey “demonstrated that blood circulates via dissections and various other experimental techniques” — making Harvey the correct answer for demonstrating blood circulation specifically

The printing press enabled Harvey's findings, published in Exercitatio Anatomica de Motu Cordis et Sanguinis in Animalibus (1628), to reach the international scientific community, contributing to the rapid accumulation of medical knowledge in the 17th century.
