The lungs are generally considered the last major organ to fully develop. This crucial development typically concludes around 37 weeks of gestation. Their complete maturation is significant because fully developed lungs produce a chemical affecting the body's hormones, preparing the fetus for life outside the womb.
Fetal Lung Development: A Closer Look
Several sources confirm the lungs' late development. The timing of complete development can vary, but it consistently falls within the later stages of pregnancy. This late maturation highlights the lungs' complex structure and vital role in respiration, making them a key focus during the final stages of fetal development.
-
Key Fact: The final stages of fetal development are focused on preparing the fetus for life outside the womb, with lung maturity being a critical aspect of this preparation.
-
Reference: Family Doctor and Cleveland Clinic both highlight the importance of lung development in the final stages of pregnancy.

Further Insights: The American Lung Association (https://www.lung.org/blog/how-young-lungs-develop) provides more detailed information on the process of lung development in the fetus, emphasizing the variability in development rates and the importance of reaching full maturity.
While other organs also continue developing throughout pregnancy, the lungs stand out due to their late maturation and the significant impact this has on the overall readiness of the fetus for birth. The timing of lung maturity plays a crucial role in determining a baby's ability to breathe independently after birth.
