Claude Bernard

Claude Bernard was a French physiologist regarded as the father of experimental medicine. Following the work of William Beaumont he opened artificial fistulas in animals to study their digestive systems. He demonstrated the role of the pancreas in digestion, discussed the presence and function of glycogen in the liver (1856), and in 1851 reported the existence of the vasomotor nerve.
