Dynamics of changes of length and diameter of different parts of common bile duct has been traced on 62 corpses of human fetuses and newborns by means of macro- and microscopic preparation and morphometry methods. It has been established that during the fetal period of human ontogenesis the common bile duct growth has an asynchronous character with alternation of the periods of acceleration (5–7 and 9–10 months) and delay (8 months). The features of the common bile duct growth are caused by different character of growth of its parts.
