Fetal Development Sequence

    Directions- Cut and paste in order what comes first and second in order and so on.

     

    · By now the fetus is 2 1/2 to 3 inches long and is fully formed. He has begun swallowing and kicking. All organs and muscles have formed and are beginning to function.
     
    · 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. He weighs between 4 and 6 pounds.
     
    · 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.
     
    · Upon implantation, complex connections between the mother and embryo develop to form the placenta.
     
    · A protective coating called vernix caseosa begins to form on baby's skin. By the end of this month, your baby will be nearly 8 inches long and weigh almost a pound.
     
    · The embryo may float freely in the uterus for about 48 hours before implanting.
     
    · By the end of this month, the embryo is about 1/10 of an inch long. The heart, which is no larger than a poppy seed, has begun beating.
     
    · Egg surrounded by sperm. A sperm penetrates the egg and conception occurs. It is called a zygote until it reaches the uterus in 3-4 days.
     
    · By the end of this month, your baby weighs about 3 1/2 pounds and is about 12 inches long. His body is well-formed. Fingernails cover his fingertips
     
    · The embryo is about 1 inch long and has distinct, slightly webbed fingers. Veins are clearly visible. The heart has divided into right and left chambers.
     
    · An egg goes down the fallopian tube after ovulation; if a sperm makes its way from the vagina through the uterus to the egg within 24 hours, conception is likely to occur.
