Her lungs are producing a substance called surfactant 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.
Toxoplasmosis: A disease caused by the sporozoan Toxoplasma gondii, found in cat feces. It can be fatal to a fetus.

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.
Syphilis: Sexually transmitted venereal infection caused by treponema pallidum.

A medication used to help infants suffering from or at great risk of respiratory distress syndrome. Surfactant is a soapy material inside the lungs of adults and mature infants that helps the lung to function. Without surfactant, the air sacs tend to collapse on exhalation.

Your baby has surfactant, 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 surfactant. Surfactant 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.

The more premature babies are, the less surfactant is present in their lungs. Surfactant is a substance that coats the tiny alveoli inside the lungs, helping them to stay inflated so that they have the best surface area available for oxygen to pass into the blood in sufficient amounts.

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

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. The fetal ear is almost completely developed both inside and out.

Your baby's lungs continue to mature, producing increasing amounts of 'surfactant'. This is a fatty liquid (called phospholipid) that lines their lungs, keeping them moist and helping the sacs within them (called alveoli) to expand efficiently for breathing.

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 baby is still busy producing surfactant, a fat/protein mix that keeps her lung sacs from sticking together when she takes her first breaths.
Your baby has likely reached her birth weight of somewhere between 6 and 9 pounds, about a third of which is accounted for by her head.

Your babies development is almost complete, their lungs are now coated in surfactant, a substance which helps them to make the transition from breathing amniotic fluid in the womb to breathing oxygen at birth, and their sucking reflex is developing to enable them to feed effectively.

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. Along with the production of surfactant, the network of blood vessels servicing the lungs increases.

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 lungs are maturing and surfactant 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.

Your baby's lungs start to make surfactant. This substance helps your baby's lungs get ready to breathe.
Week 27
Your baby is doing lots of kicking and stretching. Her lungs and nervous system continue to develop. This week marks the end of your second trimester.

The final preparations for independent existence occur during the ninth month. Surfactant, 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. Much of the lanugo disappears.

Most of the lanugo is gone as the baby prepares for its final womb days. The lungs are maturing and surfactant production is increasing.
The baby can't move too much anymore as its womb space has become very crowded.
The average size baby is over seven pounds at this point.

The air sacs are developed and the baby’s first breathing exercise can begin this week. Surfactant continues to develop, which will help the lungs expand once the baby is born.
The nostrils, which had remained closed till now, also begin to open up.

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. The baby practices breathing by inhaling amniotic fluid into developing lungs.

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 lungs don't always open up reliably, and baby may have episodes of apnea during which he stops breathing. A drug called surfactant may be given to help the lungs open.

At this point, your little one can swallow, urinate and make breathing movements. In preparation for breathing, his lungs secrete a surfactant, 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 surfactant which will help the air sacs to inflate once he's born.

Seeing as how your hips have separated 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 being ...

The baby now reacts to light and sound. Special cells in the lungs begin to secrete a substance called surfactant that helps to keep the lungs open and able to absorb oxygen. The chance of survival increases now with each subsequent week of pregnancy.

His lungs are developing "branches" of the respiratory "tree" as well as cells that produce surfactant, a substance that will help his air sacs inflate once he hits the outside world. His skin is still thin and translucent, but that will start to change soon.

Birth injury may occur due to the baby's large size and difficulty being born.
