Answer

Discovery of the First Hormone

The first hormone to be discovered by scientists was secretin.

Discovery Process

In 1902, two British physiologists, William M. Bayliss and Ernest H. Starling, were conducting experiments on the digestive system of dogs. They found that the introduction of acid into the small intestine caused the pancreas to secrete a fluid that neutralized the acid.

Role of Secretin

Bayliss and Starling believed that a chemical messenger was responsible for this response and named it secretin because it was secreted from the intestinal lining. They found that secretin was released into the bloodstream and traveled to the pancreas, stimulating it to secrete the fluid that neutralized the acid.

Significance of Discovery

The discovery of secretin was groundbreaking because it was the first time a chemical messenger had been identified as a hormone. This discovery opened the door to further research on the endocrine system and the role of hormones in physiological processes.

Conclusion

In conclusion, the first hormone discovered by scientists was secretin, which was identified by William M. Bayliss and Ernest H. Starling in 1902. This discovery was significant because it marked the beginning of the study of hormones and their role in physiological processes.
