What you should know about the baby at 25 weeks pregnant fetal development is that the little one is 13 inches long and he or she weighs more than 1.5 pounds.
There is a lot going on with him or her and he or she is developing in every possible way.
Things to know
If you could see the baby, you would notice that his or her skin is turning pink. This doesn’t mean that the little one is overheated. In fact the amniotic fluid surrounding the baby has the perfect temperature and it always has the same temperature protecting the baby against fluctuations.
The coloration changes are caused by the development of the small blood vessels that are also known as capillaries. These are getting filled with blood. A bit later the lung’s blood vessels will also develop and so they will be closer to maturity.
Work in progress
Nonetheless if you are thinking about the baby at 25 weeks pregnant fetal development you should know that there is still a lot of work to be done. Although the lungs are already developing surfactant (this is a substance that makes the air sacks expand after the little one is born), they are still underdeveloped.
When thinking about the 25th week of pregnancy baby development you should know that at this point the lungs of the baby can’t send oxygen to the blood stream and the blood can’t release carbon dioxide either when exhaling. Naturally breathing isn’t only about the lungs. Until this moment, the nostrils of the baby were plugged and this is the time when they start to open.
This makes it possible for the baby at 25 weeks pregnant fetal development to practice breathing. Naturally there is no air to practice on, but there is a lot of amniotic fluid, which is the next best thing. It is important for the baby to get the hang of it even before he or she gets born.
