Introduction
If you are expecting a baby or just curious about the development of a fetus, you may be wondering when a baby starts to develop. The truth is, the development of a fetus is a complex process that takes place over several weeks and months. In this article, we will take a comprehensive look at when a baby starts to develop and the different stages of fetal development.
First Trimester
The first trimester of pregnancy is a crucial stage of fetal development. It is during this time that the fetus develops from a single cell to a fully formed human being. The first trimester lasts from week one to week twelve of pregnancy.During the first four weeks of pregnancy, the fertilized egg travels down the fallopian tube and implants itself in the lining of the uterus. This is where the placenta will develop, which will provide the fetus with nutrients and oxygen.By week five, the fetus has developed a heartbeat, and by week six, the arms and legs begin to form. By week eight, all major organs have formed, and the fetus is now considered a fetus rather than an embryo.
Second Trimester
The second trimester of pregnancy is when the fetus begins to grow rapidly. This stage of fetal development lasts from week thirteen to week twenty-six.During the second trimester, the fetus grows from about three inches to about fourteen inches long. The fetus also develops hair, nails, and teeth buds. By week twenty, the fetus can hear and respond to sounds outside of the womb.
Third Trimester
The third trimester of pregnancy is the final stage of fetal development. This stage lasts from week twenty-seven until birth.During the third trimester, the fetus continues to grow and develop. The fetus gains weight and develops a layer of fat under the skin. This layer of fat helps to regulate the baby’s body temperature after birth. The fetus also begins to practice breathing by inhaling and exhaling amniotic fluid.
