Ernest Starling

Ernest Henry Starling (17 April 1866 – 2 May 1927) was a British physiologist who contributed many fundamental ideas to this subject. These ideas were important parts of the British contribution to physiology, which at that time led the world.

He made at least four significant contributions: 1. In the capillary, water is forced out through the pores in the wall by hydrostatic pressure and driven in by the osmotic pressure of plasma proteins (or oncotic pressure). These opposing forces approximately balance; which is known as Starling's Principle. 2. The discovery of the hormone secretinwith his brother-in-law William Baylissand the introduction of the word hormone. 3. The analysis of the heart's activity as a pump, which is known as the Frank–Starling law. 4. Several fundamental observations on the action of the kidneys. These include evidence for the existence of vasopressin, the anti-diuretic hormone. He also wrote the leading textbook of physiology in English, which ran through 20 editions. Provided by Wikipedia
