Fetus: Biology

The fetus is an unborn offspring in its embryonic and later stages of development in the uterus of a pregnant woman. During the 9 months of pregnancy, the fetus undergoes dramatic changes in both size and structure as it develops from a single cell to a mature human being. It is dependent on the mother for nutrition and oxygen, vital for proper growth and development. By studying fetal biology, scientists can gain a better understanding of how a fetus develops and provide valuable insight into the health and well-being of a developing fetus. This knowledge can be used to diagnose, detect, and treat diseases, as well as to improve the safety and comfort of pregnant women and their babies.
