According to embryology‚ all vertebrate embryos follow a common developmental path due to their common ancestry. All have a set of very similar genes that define their basic body plan. As they grow‚ the differences that will distinguish the embryos as adults become more and more apparent. The study of this development can yield insights into the process of evolution. This branch of embryology that compares and contrasts embryos from different species is called Comparative Embryology

when a woman’s ovary releases an egg cell and it flows in the fallopian tube where one of the thousand of sperm cells would fertilize the egg. After getting fertilized‚ the egg would swim down to the uterus and there is where it would develop into an embryo‚ then fetus‚ and‚ finally‚ a baby. But in ectopic pregnancy‚ it is totally different. Ectopic pregnancy is a pregnancy in which the egg cell is fertilized and develops outside the uterus‚ usually occurs in the fallopian tube. 98% of ectopic pregnancy

HUMAN BODY PLAN: STUDY of ANATOMY and PHYSIOLOGY THE HUMAN BODY PLAN The human body begins to take shape during the earliest stages of embryonic development. While the embryo is a tiny hallow ball of dividing cells‚ it begins forming the tissues and organs that compose the human body. By the end of its third week‚ human embryo has bilateral symmetry (a body plan in which the left and right sides mirror each other) and is developing vertebrate characteristics that will support an upright body.
