From the ninth week of gestation until birth, the developing human is called a fetus. What term is used for this stage?

Explanation:
The main idea is understanding prenatal development stages by gestational age. Starting at the ninth week, the developing human is in the fetal period, which continues until birth. The embryo stage ends around eight weeks when most organs and body structures are forming; once week nine begins, growth and maturation of those structures characterize the fetal phase. The term fetus specifically denotes this later prenatal stage focused on development and refinement of already-formed systems. Neonate refers to a newborn after birth, zygote is the fertilized egg from conception, and embryo describes the earlier stage up to about eight weeks.
