As an expectant mother, you may be curious about how your baby’s lungs are developing. After all, the lungs are one of the most important organs in the body, responsible for breathing and oxygenation. In this article, we will explore whether or not your baby’s lungs are developed at 34 weeks.

What Happens at 34 Weeks?

At 34 weeks, your baby is now considered late preterm. This means that although they are not yet full-term, they are getting close to being ready for delivery. Their lungs have been developing over the entire course of the pregnancy, and by 34 weeks, they should be fully formed.

What Does Fully Formed Mean?

When we say that a baby’s lungs are fully formed, we mean that they have all of the necessary structures to breathe on their own. This includes the air sacs, which are responsible for oxygen exchange, as well as the bronchioles and alveoli, which help to distribute air throughout the lungs.

Why Is Lung Development Important?

Lung development is crucial for a baby’s survival after birth. If a baby is born prematurely, their lungs may not be fully developed, which can lead to breathing difficulties and other complications. By 34 weeks, your baby’s lungs should be developed enough to function properly outside of the womb.
