Day 1: Day 1: Conception takes place Days 7-14: Days 7-14: Fertilized Egg Implants in the Wall of the Mother ’ s Uterus Days 1-14 = Period of the Zygote ***“Zygote” means fertilized egg
Day 18: Day 18: Heart begins to beat Day 21: Day 21: Pumps own blood through separate closed circulatory system with its own blood type Day 28: Day 28: Eye, ear and respiratory system begins to form
3 Stages of Fetal Development:
Conception (Day 1) Fertilized Egg is Implanted in the Wall of the Mother ’ s Uterus (~ Day 14) Two Weeks Zygote grows to be about the size of a pin head
2 Weeks After Conception 2 Months After Conception *Attachment of Umbilical Cord to uterus *All Organs form *Amniotic Sac & Fluid formed 6 Weeks
From the End of the 2nd Month of Pregnancy BIRTH 8 Months
First Month Cell multiplication begins Egg attaches to uterus lining The heart, which is no larger than a poppy seed, has begun beating.
Two Months The embryo is about ¼” inch long and has distinct, slightly webbed fingers. Veins are clearly visible. The heart has divided into right and left chambers. Bones begin to form Development of internal organs The embryo is attached to the mother by the umbilical cord.
Three Months By now the fetus is 1 inch long and is fully formed. All organs and muscles have formed but are immature. Eye lids fused. Fingers and toes almost complete
Four Months Fetus is 3 inches long Can suck thumb, swallow, hiccup and move. Facial features are clearer.
Five Months Fetus is 8-10” long weighing almost a pound. Lanugo develops Fetus is more active Hair, eyelashes, and eybrows appear
Six Months Baby's lungs are filled with amniotic fluid, and he has started breathing motions. If you talk or sing, he can hear you. Fat deposits under skin Vernix develops
Seven Months By the end of the seventh month, your baby weighs about 1 1/2 -2lbs and is about 10-12 inches long. Fetus is active, then rests.
Eight Months Your baby is gaining about half a pound per week, and layers of fat are piling on. He has probably turned head-down in preparation for birth. Fetus may react to noise with jerking actions.
Nine Months Your baby is a hefty 6 to 9 pounds and measures between 19 and 22 inches. As he becomes more crowded, you may feel him move around less. Disease-fighting antibodies are taken in from mother’s blood Fetus “drops” into the pelvis and is ready for birth
Pregnancy is Broken Up into Trimesters
