Delivery of a baby 3D Animation

The development of a fetus occurs in several stages each marked by significant milestones and changes.
Heres an overview: Embryonic Stage Weeks 1-8: Fertilization of the egg by sperm occurs forming a zygote. The zygote undergoes rapid cell division forming a blastocyst. Implantation occurs in the uterine wall around day 6-7 after fertilization. Cells begin to differentiate into three primary germ layers: ectoderm endoderm and mesoderm. Organs and major body structures start to develop such as the neural tube heart limbs and basic facial features. Fetal Stage Weeks 9-12: The embryo is now referred to as a fetus. Major organs continue to develop and become more defined. Limbs elongate and fingers and toes begin to form. Facial features become more distinct including eyes ears and nose. The fetus begins to move spontaneously though these movements are not usually felt by the mother yet. External genitalia start to differentiate although gender may not be identifiable via ultrasound until later in this stage. Second Trimester Weeks 13-26: Rapid growth and development continue. Organs mature and become functional. Fetal movements become more pronounced and may be felt by the mother quickening. Vernix caseosa a protective waxy substance covers the skin. Hair eyebrows and eyelashes develop. Fingernails and toenails form. The fetus can hear sounds from the outside world and brain activity increases. Third Trimester Weeks 27-birth: The fetus continues to grow and mature rapidly. Lung development accelerates with the fetus practicing breathing movements. Fat deposition increases helping to regulate body temperature. Brain development continues with further refinement of neural connections. Fetal movements may become more restricted due to limited space in the uterus. The fetus settles into a head-down position in preparation for birth although variations in position are common. By the end of this stage the fetus is fully developed and ready for birth with all major organs and systems in place.
