The Soviet Union became a prominent centre for the study of physiology, and the fact that the 15th International Physiological Congress of August, was held in Leningrad and Moscow clearly shows that it was acknowledged as such. Pavlov performed and directed experiments on digestion, eventually publishing The Work of the Digestive Glands inafter 12 years of research.
Petersburg, he investigated cardiac physiology and blood pressure regulation.
