Fetal development is the process by which a fertilized egg develops into a fetus and eventually a baby. This process involves a series of intricate biological changes and growth stages, from the formation of organs and limbs to the development of the central nervous system. Fetal development typically lasts around 40 weeks, starting from conception and ending with birth. This area of research is crucial for understanding how developmental abnormalities or environmental factors can impact the health and well-being of the fetus. Additionally, studying fetal development can provide insights into potential interventions or treatments to optimize growth and development in utero.
