How baby is formed as an embryo

1.	How baby is formed as an embryo
Answer» During fertilization, the sperm and egg unite in one of the fallopian tubes to\xa0form\xa0a zygote. Then the zygote travels down the fallopian tube, where it becomes a morula. Once it reaches the uterus, the morula becomes a blastocyst. The blastocyst then burrows into the uterine wall — a process called implantation.\xa0The distinction\xa0between embryo\xa0and\xa0fetus\xa0is made based on gestational age. An\xa0embryo\xa0is the early stage of human development in which organs are critical body structures are formed. An\xa0embryo\xa0is termed a\xa0fetus\xa0beginning\xa0in the\xa011th week of\xa0pregnancy, which is the 9th week of development after fertilization of the egg.
