This is especially true for babies that present certain issues or are born prematurely. This medication accelerates the maturity process. To facilitate vital functions, their little lungs must be perfectly developed once pregnancy reaches full term. This includes the pulmonary alveoli and bronchi, as well as a substance known as surfactant.

Embryonic Development of the Respiratory System

I am almost 32 weeks pregnant and have developed severe pre-eclampsia. I am on complete bed rest until I deliver. My question is my doctor wants to start giving steroid injections soon to help mature our sons lungs. I have had steroid shots before, but not while I was pregnant the other 2 times.

Development of the respiratory system begins early in the fetus. It is a complex process that includes many structures, most of which arise from the endoderm. Towards the end of development, the fetus can be observed making breathing movements. Until birth, however, the mother provides all of the oxygen to the fetus as well as removes all of the fetal carbon dioxide via the placenta. The development of the respiratory system begins at about week 4 of gestation.
