Diary of an Unborn Child
Chronology of the New Life
- Immediately upon fertilization, cellular development begins. Before
implantation the sex of the new life can be determined.
- At implantation, the new life is composed of hundreds of cells and has
developed a protective hormone to prevent the mother's body from rejecting
it as a foreign tissue.
- At 17 days, the new life has developed its own blood cells; the placenta
is a part of the new life and not of the mother.
- At 18 days, occasional pulsations of a muscle - this will be the heart.
- At 19 days, the eyes start to develop.
- At 20 days, the foundation of the entire nervous system has been laid
down.
- At 24 days, the heart has regular beats or pulsations.
- At 28 days, 40 pairs of muscles are developed along the trunk of the new
life; arms and legs forming.
- At 30 days, regular blood flow within the vascular system; the ears and
nasal development have begun.
