"Introduction to the study of experimental medicine" is an outstanding work of the French physiologist and physician Claude Bernard. In this book, the author expresses his ideas about research methods in medicine, solving the problem of "living" and "inanimate" in biology, and also considers important questions about the functions of the body and the mechanisms of its adaptation to the external environment. The book provides the reader with an in-depth understanding of the processes that take place in a living organism, and has become one of the foundational works in the field of physiology and medicine. In his work, Bernard leads the reader to a non-standard approach to medical research and the discovery of new ways of development of modern science.
