Medical Training and Revolutionary Discoveries
Medical education was getting a serious upgrade during this period. Apothecaries and surgeons received better training, partly because new warfare technology created different types of wounds that needed treating. More chemicals became available, giving apothecaries fresh ingredients to work with.
Vesalius was the medical rebel who found around 300 mistakes in Galen's work through human dissection. He proved that humans have one jawbone, not two, and encouraged doctors to learn from actual bodies rather than dusty textbooks. This caused massive controversy but made anatomy central to medical study.
William Harvey made the breakthrough discovery about blood circulation. Through dissecting human corpses and cold-blooded animals, he proved that blood flows in one connected system and that the heart acts as a pump. However, his discovery had little immediate impact on actual treatment.
Remember: These discoveries were revolutionary for understanding the human body, but they didn't immediately change how doctors treated patients - that would come later.
