Question

Why embryo in humans is called a fetus?

Answer 1

Fetus:

1. The levels of cell specialization in the fetus are extremely specialized.
2. The term "fetus" describes the infant at its most advanced stage.
3. Beginning in the eleventh week of pregnancy, an embryo is referred to as the fetus.
4. Embryogenesis is the term used to describe the embryo's development.
5. Blastocysts develop following fertilization. The blastocyst then changes into an embryo.
6. The embryo is then known as a fetus after the 11th week of pregnancy (about 2.5 months).
7. The embryo comes first in the timeline, followed by Fetus.
