Review Questions

• How did humoral theory influence the practice of bloodletting in ancient medicine?
  • Humoral theory greatly influenced bloodletting by suggesting that imbalances in bodily fluids caused illness. Practitioners believed that removing blood could restore this balance, treating various ailments. The understanding of health during this time was closely tied to these beliefs, making bloodletting a common therapeutic approach.
• Discuss the methods used for bloodletting and how they reflect the medical practices of the time.
  • Bloodletting employed several methods such as venesection, where a vein was cut to draw blood, and leech therapy, where leeches were applied to the skin. Cupping was also popular, using suction to create bruises that drew blood to the surface. These methods illustrate the rudimentary understanding of anatomy and physiology at the time, as well as the reliance on observable effects rather than scientific evidence.
• Evaluate the reasons behind the decline of bloodletting as a medical practice in the 19th century.
  • The decline of bloodletting can be attributed to emerging scientific discoveries that contradicted humoral theory, such as germ theory and better understandings of disease processes. Medical professionals began to recognize that excessive blood removal could be harmful rather than beneficial. Additionally, the development of more effective treatments led to a shift in focus towards evidence-based medicine, reducing reliance on outdated practices like bloodletting.
