The second trimester of pregnancy begins at 13 weeks. Between 13 and 15 weeks, the four lobes of the cerebral cortex have developed. The face continues to mature: the nasal plugs disappear, fat deposits fill out the cheeks and tooth development begins.

Growth of the lining of the large airways is well underway with cilia appearing for the first time at 13 weeks. Cilia are tiny hair-like projections extending from cells lining the airway. They serve to trap and move mucous and debris toward the throat. Cilia provide an important defense against foreign material and some infections. Mature cells lining the airways will have approximately 200 cilia each.

From a teething toddler to a child losing her baby teeth, our teeth go through many stages – the first of which starts in the womb where tooth development begins by 13 weeks.

The baby’s feet are now ten times the length they were at 7 weeks!

The baby’s entire body, except for parts of the scalp, responds to light touch.

Lord, thank you for the privilege of modern science that teaches us so much about the growth of the children in the womb.
You have taken away the excuses, O God, of those who would claim they do not know who is in the womb.
And you have given to the advocates of life a beautiful and motivating tool to call for the protection of our youngest brothers and sisters.
Lord, as we continue to participate in this project, give us a deeper love for these children and make us effective advocates for their right to life.
We pray through Christ our Lord. Amen.
