What did Bayliss and Starling's research and experiments ultimately lea to?

Bayliss and Starling's research led to the discovery of the hormone secretin, which plays a crucial role in regulating digestive processes. Their experiments demonstrated how the presence of acid in the duodenum stimulates the secretion of this hormone, prompting the pancreas to release bicarbonate to neutralize stomach acid. This work laid the foundation for understanding hormonal regulation in the digestive system and contributed significantly to the field of endocrinology. Their findings highlighted the complex interplay between the nervous and endocrine systems in controlling bodily functions.
