The evolution of digestive system knowledge spans from Avicenna's 11th-century herbal remedies to the Renaissance's anatomical insights, 17th-century chemical theories, and the 20th-century focus on enzymes and hormones. Discoveries like the role of H. pylori in peptic ulcer disease have significantly advanced our understanding of gastrointestinal pathophysiology, reflecting centuries of scientific progress.
