Pregnancy is a wonderful and exciting time for expecting mothers. Throughout the nine months of pregnancy, a baby’s body undergoes an incredible transformation. There are many stages in fetal development, and each one is unique and fascinating. However, one question that often comes up is, “What body parts does a baby develop last during pregnancy?”

The Brain and Nervous System
One of the last body parts to develop in a baby during pregnancy is the brain and nervous system. The brain is responsible for controlling all the functions of the body, and it takes time to develop fully. During the final trimester, the brain goes through a period of rapid growth and development, and this continues after birth. By the time a baby is born, their brain is already 25% of its adult size.
The Lungs
Another body part that develops last during pregnancy is the lungs. The lungs are responsible for breathing, and they do not fully mature until the final weeks of pregnancy. The lungs produce a substance called surfactant, which helps keep the air sacs in the lungs from collapsing. Without enough surfactant, breathing can be difficult for a newborn baby.
The Liver
The liver is another body part that develops last during pregnancy. The liver is responsible for processing nutrients and producing bile, which helps with digestion. During the final trimester of pregnancy, the liver grows rapidly to prepare for the baby’s nutritional needs after birth.
The Immune System
The immune system is also one of the last body parts to develop during pregnancy. The immune system is responsible for fighting off infections and diseases, and it takes time to develop fully. However, babies are born with some immunity passed down from their mothers, which helps protect them during the first few months of life.
The Skin
Finally, the skin is one of the last body parts to develop during pregnancy. The skin is the largest organ in the body, and it provides a barrier between the baby and the outside world. During the final weeks of pregnancy, a waxy substance called vernix caseosa covers the baby’s skin to protect it from the amniotic fluid. This substance also helps regulate the baby’s body temperature after birth.
In Conclusion
The development of a baby’s body is an incredible and complex process. While there are many body parts that develop throughout pregnancy, the brain, lungs, liver, immune system, and skin are some of the last to fully mature. It’s important for expecting mothers to take care of themselves and their growing babies during this time, so that their little ones can be born healthy and strong.
