Abstract

The term conceptus (products of conception) includes all the structures that develop from the zygote: the embryo, or fetus, and the placenta with its membranes. The developing human is considered to be an embryo from conception until the end of the eighth week, by which time all major organ systems have been formed. From the beginning of the ninth week until birth, the developing human is called a fetus.
