Fetal Development -All 3 Trimesters

"The fetus isn't really like a baby at all until very late in the pregnancy when abortion is restricted"  - pro-choice supporter

CORRECTION:  THE TRUTH is that by 4 weeks nearly all of the baby's major organs and body systems are in place and beginning to form.  And by the end of 12 weeks...the organs and body systems are fully formed!  Furthermore, now that all the major organs and systems have formed in the fetus, the following six months will be spent growing!  (Taken from the Univeristy of Alabama hospital website- referenced below, and available at any other credible fetal development source... because those are the FACTS.)

Fetal Development During The First Trimester

The most dramatic changes and development occur during the first trimester. During the first eight weeks, a fetus is called an embryo. The embryo develops rapidly and by the end of the first trimester it becomes a fetus that is fully formed, weighing approximately 1/2 to one ounce and measuring, on average, three to four inches in length.

Just as each child grows and matures at different rates and at different times, so does that same child as it begins its life in the womb. The chart provided below provides benchmarks for most normal pregnancies. However, each fetus develops differently.

by the end of 4 weeks
  • all major systems and organs begin to form
  • the neural tube (which becomes the brain and spinal cord), the digestive system, and the heart and circulatory system begin to form
  • the beginnings of the eyes and ears are developing
  • tiny limb buds appear (which will develop into arms and legs)
  • the heart is beating
by the end of 8 weeks
  • all major body systems continue to develop and function, including the circulatory, nervous, digestive, and urinary systems
  • the embryo is taking on a human shape, although the head is larger in proportion to the rest of the body
  • the mouth is developing tooth buds (which will become baby teeth)
  • the eyes, nose, mouth, and ears are becoming more distinct
  • the arms and legs are clearly visible
  • the fingers and toes are still webbed but can be clearly distinguished
  • the main organs continue to develop and you can hear the baby's heartbeat using an instrument called a Doppler
  • the bones begin to develop and the nose and jaws are rapidly developing
  • the embryo is in constant motion but cannot be felt by the mother
from embryo to fetus After 8 weeks, the embryo is now referred to as a fetus (which means offspring or developing human from 8 weeks to birth).

Although the fetus is only 1 to 1 1/2 inches long at this point, all major organs and systems have been formed.

during weeks 9-12
  • the external genital organs are developed
  • fingernails and toenails appear
  • eyelids are formed
  • fetal movement increases
  • the arms and legs are fully formed
  • the voice box (larynx) begins to form in the trachea

The fetus is most vulnerable during the first 12 weeks. During this period of time, all of the major organs and body systems are forming and can be damaged if the fetus is exposed to drugs, German measles, radiation, tobacco, and chemical and toxic substances.

Even though the organs and body systems are fully formed by the end of 12 weeks, the fetus cannot survive independently.

Fetal Development During The Second Trimester

Now that all the major organs and systems have formed in the fetus, the following six months will be spent growing. The weight of the fetus will multiply more than seven times over the next few months, as the fetus becomes a baby that can survive outside of the uterus.

By the end of the second trimester, the fetus will be about 13 to 16 inches long and weighs about 2 to 3 pounds. Fetal development during the second trimester includes the following:

  • The fetus kicks, moves, and can turn from side to side.
  • The eyes have been gradually moving to the front of the face and the ears have moved from the neck to the sides of the head. The fetus can hear the mother's voice.
  • A creamy white substance (called vernix caseosa, or simply vernix) begins to appear on the fetus and helps to protect the thin fetal skin. Vernix is gradually absorbed by the skin, but some may be seen on babies even after birth.
  • The fetus is developing reflexes such as swallowing and sucking.
  • The fetus can respond to certain stimuli.
  • The placenta is fully developed.
  • The brain will undergo its most important period of growth from the 5th month on.
  • Fingernails have grown on the tips of the fingers and toes, and the fingers and toes are fully separated.
  • The fetus goes through cycles of sleep and wakefulness.
  • Skin is wrinkly and red, covered with soft, downy hair (called lanugo).
  • Hair is growing on the head of the fetus.
  • Fat begins to form on the fetus.
  • Eyelids are beginning to open and the eyebrows and eyelashes are visible.
  • Fingerprints and toeprints have formed.
  • Rapid growth is continuing in fetal size and weight.
  • The 20th week marks the halfway point of the pregnancy.

A fetus born at the end of 24 weeks may survive in a neonatal intensive care unit.

Fetal Development During The Third Trimester

During the third trimester, the fetus continues to grow in size and weight. The lungs are still maturing and the fetus begins to position itself head-down. By the end of the third trimester, the fetus is about 19 to 21 inches long and weighs, on average, six to nine pounds. Fetal development during the third trimester includes:

  • The fetus can see and hear.
  • The brain continues to develop.
  • The bones of the skull remain soft to make it easier to pass through the birth canal.
  • For many babies, the irises of the eyes are slate blue. The permanent eye color will not appear until several days or weeks after birth.
  • The fetus can suck its thumb and has the ability to cry.
  • By 38 to 40 weeks, the fetus' lanugo has disappeared almost completely.
  • By 38 to 40 weeks, the lungs have matured completely.
  • The baby is covered in vernix caseosa (or simply called vernix), a creamy, protective coating on the skin.
  • The head will usually turn downward during the last couple of weeks of pregnancy.

So much for the pro abortion rationale that the developing fetus in the 1st trimester is "nothing like a baby"!  LIE, LIE, LIE.  Typical to the pro abortion movement... Full of distortions and lies!
