A developing baby is considered a fetus beginning in the 11th week of pregnancy. The terms embryo and fetus both refer to the developing baby inside the mother’s womb (uterus). The distinction between embryo and fetus is made based on gestational age. An embryo is the early stage of human development in which organs are critical body structures are formed. An embryo is termed a fetus beginning in the 11th week of pregnancy, which is the 9th week of development after fertilization of the egg. A zygote is a single-celled organism resulting from a fertilized egg.
