Her lungs are producing a substance called that allows the lungs to inflate and deflate without collapsing or sticking together.
Blood vessels in your baby's lungs also are growing and developing in preparation for breathing.

Surfactant: A wetting agent secreted by the cells lining the alveoli of the lungs to prevent the lung walls from sticking together.


A substance produced in the lungs that prevents the tiny air sacs (alveoli) in the lungs from collapsing and sticking together by reducing surface tension.

Surfactant: Phospholipid present in the lungs. Controls surface tension of lungs. Premature babies often lack sufficient amounts of surfactant to breathe without assistance.

Your baby has , which helps baby breathe after birth, coating the alveoli in the lungs. After this week, if your baby is born, you have less of a chance of apnea of prematurity. S/he weighs about four pounds (1.8 kilograms).

In RDS, the infant's immature lungs don't produce enough of an important substance called . allows the inner surface of the lungs to expand properly when the infant makes the change from the womb to breathing air after birth.

A substance called surfactant helps keep the air sacs in the lungs open. Babies with respiratory distress syndrome (RDS) don't produce enough surfactant and can't breathe properly.

Your baby has been developing in his lungs since around week 20. This enables him to breathe at birth.

Here's the deal: The ingredient sodium lauryl sulfate, a popular surfactant found in shampoos, has been linked to birth defects in animal studies.

Babies born before 32 weeks, and especially those weighing under 1,500g (3lb 5oz), usually have immature lungs which cannot secrete , a foamy substance that prevents the inner surfaces of the lungs from sticking together.

However, now there is surfactant being produced in your baby's lungs. Surfactant prevents your baby's lungs from collapsing outside of the uterus and the baby is able to take in air and breathe properly.

Your baby's lungs continue to mature, producing increasing amounts of ''.

Betamethasone and dexamethasone cause an immature fetus's lungs to produce a compound called surfactant. A full-term baby's lungs naturally produce surfactant, which lubricates the lining of the air sacs within the lungs.

Your babies development is almost complete, their lungs are now coated in , a substance which helps them to make the transition from breathing amniotic fluid in the womb to breathing oxygen at birth, ...

The lungs continue to develop, and this week the special moistening agent surfactant production begins. Surfactant stops the walls of the lungs from sticking together when we exhale.

The lungs are maturing and production is increasing (reducing the surface tension). The brain is still developing rapidly and the skin has become much paler in appearance due to a thick layer of fat beneath the skin.

Around 24 weeks, the baby's lungs begin to produce surfactant, which is critical to the baby's survival if born premature. Premature babies born around this time may die due to a lack of surfactant in their underdeveloped lungs.

The final preparations for independent existence occur during the ninth month. , a substance that lines the lungs and allows them to expand easily, develops. Fat is stored, and its deposition under the skin smoothes out the wrinkles.

Week 38 of Pregnancy
Your baby is producing surfactant, which will help him take those first breaths while you're producing colostrum, the precursor to breast milk.

Your baby's lungs start to make . This substance helps your baby's lungs get ready to breathe.
Week 27 ...

The lungs are developing branches of the respiratory tree and cells that produce surfactant. This is a substance that helps the air sacs inflate easily and also keeps the small air sacs in our lungs from collapsing.

Most of the lanugo is gone as the baby prepares for its final womb days. The lungs are maturing and production is increasing.
The baby can't move too much anymore as its womb space has become very crowded.

Your baby
Your baby's lungs are maturing, but they still need to develop surfactant, a substance that allows your baby to breathe after it is born.

Week 32 ...

The air sacs are developed and the baby’s first breathing exercise can begin this week. continues to develop, which will help the lungs expand once the baby is born.

A drug called surfactant may be given to help the lungs open. A premature baby may also be helped to breathe with a ventilator, a continuous positive airway pressure (CPAP) machine or supplemental oxygen.

At this point, your little one can swallow, urinate and make breathing movements. In preparation for breathing, his lungs secrete a , which will help them to remain expanded after birth and allow oxygen to enter from the air.

This is because the lungs are not producing enough surfactant. After birth, the infant will develop respiratory distress syndrome from hyaline membrane disease.

Your baby's tastebuds are fully developed. His brain is growing rapidly and his lungs are developing the substance which will help the air sacs to inflate once he's born.

and gone back together, your legs almost popped themselves out of the socket, your feet expanded and your back had a distinct pregnancy arch to it, it’s no surprise you get aches and pains sooner with your second pregnancy. As surfactant starts ...
