Lung development in humans happens over five different stages. After the embryo stage, a baby’s lungs develop in what’s called the pseudoglandular stage. During this stage, which lasts from about 5 weeks to 17 weeks gestation, the baby’s lungs can be compared to a tree trunk with branches sprouting from it.

A lung bud develops from a tube of cells called the foregut (which will itself later go on to form the gut). This bud separates into two. These two buds will eventually become your baby’s right and left lungs. Your baby makes lung movements in the womb as if they are practising breathing. The process starts at 6 weeks of pregnancy, when a small pouch of tissue called the lung bud is created from the front wall of the tube that will become your baby’s esophagus.

Over the next week, this single bud will split into two separate buds (one for each lung), and the windpipe will start to form between them. Lung development begins early in pregnancy, but is not complete until the third trimester. Between 24–36 weeks of pregnancy, the lungs begin developing alveoli – the tiny lung sacs that fill. As the baby’s lungs continue to develop, more alveoli are added during a stage called the saccular stage because the lungs begin to resemble collapsed sacs.

This stage lasts until about 35 weeks of. Scientists develop fluid-filled artificial womb to help premature babies. Kate Kelland and set up the system so that this flowed into and out of the bag.

Lung development in fetal lambs is. As the baby develops during weeks six through ten of pregnancy, the intestines get longer and push out from the belly into the umbilical cord. By the eleventh week of pregnancy, the intestines normally go back into the belly. If this does not happen, an omphalocele occurs. The omphalocele can be small, with only some of the intestines outside.

In the womb, the baby’s lungs are filled with fluid. This is normal and healthy. During labor, your baby’s body releases chemicals to help their lungs push out the fluid. The pressure of the birth.

Thinking about V-day made me think of the lung development of babies. When I was pregnant with DS I started having contractions that were very strong and started making some progress around 35 weeks. The nurses kept telling me that boys had a harder time at a younger age than girls specifically the lung development.

Thus they were considered full term. But I’ve seen a few episodes of A Baby Story and those types of shows, where the doctors have done an amnio at 37-38 weeks to test for lung development and found that the lungs weren’t fully developed, so they couldn’t induce the mom’s early like they wanted to.

Its lungs develop more fully, eyelids open, and first trimester mature and grow during this trimester.

The Lungs Before Birth In fetal life, the lungs are filled by fluid secreted by the lung epithelium; the lung fluid is essential for growth and development of the lungs and this fluid exchanges with amniotic fluid.

At birth, the lungs are approximately half-filled with fluid derived from the amniotic cavity, lungs, and tracheal glands.

Because lung fluid production slows in late pregnancy and absorption of lung fluid begins in early labor, after birth only about 35% of the original lung fluid volume needs to be cleared.151,176,187 Ventilation of the lungs leads to liquid dispersion across the pulmonary epithelium (Figure 10-15).

The lungs develop through the breathing of amniotic fluid.

Foetal lungs contain ‘lung liquid’ (LL) which is secreted by the pulmonary epithelial cells and flows out through the developing airway into the amniotic fluid or gastrointestinal tract, flushing debris from the airways as it does so.

  • Human pregnancy typically lasts around 40 weeks and is divided into three trimesters of three months. What intrigues you the most about this developmental process?

  • God is amazing. The fact that this delicate being is so safe inside the uterus and goes through all these different transformations is a frickin’ miracle. And to feel it happening inside you is another miracle.

  • To all infected, sickness, or viruses there is always a herbal treatment for it, I’m still wondering why you think you can’t get rid of an illness you where not created with.

  • “Even by fathers…”
    I don’t understand the underlying implication. Do you think they generally don’t care about the babies’ whereabouts or that they somehow ought to know this particular fact beforehand?

  • Hi there, 
    The explanation provided in this video is a myth and no longer believed to be the actual mechanism for fluid resorption in the newborn.  It is more associated with changing hormones (epinephrine, thyroxine, vasopressin, glucocorticoids) that lead to changes of sodium resorption causing fluid to be reabsorbed by the body (lymphatics).  
    This article found at:  mentions this mechanism as well 

  • I had a C-section on June 11.2014 and my baby is still in the NICU.  My baby have TRANSIENT TACHYPNEA for now,my question is to you,how long was it before he started breathing normally? I’m worry.I’m going to leave everything in God hand.


  • My question is, with advancements in modern science is it possible to inhibit the closing of that artery and have a human that can live in an amniotic environment? or what I also want to know is it possible with science to expand the time a human develops in the womb for  FEW EXTRA MONTHS? can one delay birth? can we nurture a life inside an artificial womb>?

  • 3:6. He is the One Who is shaping you in the wombs as He wishes; there is no Deity except Him, the Exalted, the Wise.

    It is told in verse 59: 24 that He is Lord Allah, the Creator of the soul, the Maker of the body and the Synchronizer of the soul with body; to Him belongs names submitted by the Best Book Adhikr; whatever in Heavens and in Earth glorifies Him, He is the Exalted, the Wise. See explanation 2: 28 and 129.

  • My mom got delivery during her 6 and half months of pregnancy due to some health issues….as child i used to be very week.. i am 19 years old now….living a healthy life….

  • Very good video, except the uterus does not shrink back to its original size immediately after delivery. It takes several weeks. Let’s also remember to acknowledge postpartum bodies!

  • It’s amazing to actually feel that there is something moving (kicking here and there) inside my belly, and to know that this is gonna be a beginning of
    a human being
    That will grow up and have a life, pretty much like how we are living now.
    It’s such a magical experience that only a woman could have ✨
