What is the period that extends from the beginning of the 9th week until the end of intrauterine life called?

A transformation of an embryo into a fetus constitutes a gradual process, but the change is important because it means that the embryo has developed into a recognizable human being and has the beginnings of all major systems.
The development during the fetal period is related to the rapid growth of the body and the differentiation of tissues, organs, and systems.
The rhythm of body growth during the fetal period is very fast, and the weight gain of the fetus is very large during the last weeks.
The length of the fetus is usually expressed as vertex-buttock length (V-N), which is the size in a seated position.
