When Does Surfactant Begin To Be Expressed In The Fetal Lung

Surfactant is a substance that helps to move fluids through the lungs and throughout the body. It plays an important role in maintaining healthy lung function during pregnancy and childbirth.

The fetus’s lungs do not yet have the ability to produce surfactant on their own, so it must be provided by the mother. The exact amount of surfactant needed for the fetus varies depending on its size and weight, but it typically ranges from around 1 to 2 milligrams per liter of blood (mL/L).
Surfactant is produced by specialized cells called alveolar macrophages in the lungs. These cells contain enzymes that break down lipids into smaller droplets, which are then absorbed into the bloodstream. This process creates surfactant molecules, which help to dissolve fats and oils in the air we breathe and loosen them in the lungs.
Once the surfactant molecules reach the fetus’s lungs, they mix with other substances in the air to form larger droplets that can be easily absorbed by the fetus’s tissue. This allows the lungs to expand and fill up with air, enabling the fetus to breathe and grow.
During pregnancy, the mother’s levels of surfactant may fluctuate due to changes in hormone levels. If the mother has a low level of surfactant, her fetus may have difficulty breathing and may require more frequent oxygen therapy to maintain adequate lung function.
In addition to improving lung function, surfactant also plays a critical role in the development of the fetus’s cardiovascular system. It helps to thin the blood and decrease blood pressure, which can reduce the risk of heart problems later in life.

Overall, surfactant is essential for the health of both the mother and the fetus during pregnancy. By providing the necessary substance to support healthy lung function and development, surfactant helps to ensure a safe and healthy pregnancy.
