stages of fetal development

Fetal development begins with the formation of the embryo, which quickly grows and develops organs and structures during the first trimester. By around 12 weeks, the fetus is small but has recognizable features like fingers and toes. In the second trimester, the fetus continues to grow, with movements felt and development of muscles, senses, and facial features. The third trimester involves rapid growth, brain development, and maturation of organs in preparation for birth. Overall, fetal development is a gradual process where tissues and systems become more complex, culminating in a fully developed baby ready for life outside the womb.
