Fetal Development
Fetal development occurs in three main stages: the germinal stage (weeks 1-2), embryonic stage (weeks 3-8), and fetal stage (weeks 9-40). In the germinal stage, the fertilized egg implants in the uterus. During the embryonic stage, major organs and structures, like the heart and brain, begin to form. The fetal stage involves growth and maturation of these organs. By the end of pregnancy, the fetus is fully developed, ready for birth. This complex process is influenced by genetics and the mother's health, ensuring the baby's proper growth and development.

Fetal development refers to the stages that a human embryo undergoes as it grows into a fully formed baby during pregnancy. It typically lasts about 40 weeks and is divided into three trimesters. In the first trimester, major organs and body systems begin to form. The second trimester sees rapid growth, with distinct features like limbs and facial structures developing. By the third trimester, the fetus matures, gaining weight and preparing for birth. Throughout this process, factors like genetics, nutrition, and environment play a crucial role in healthy development.

Fetal development refers to the stages a fetus goes through from conception to birth. It begins when a sperm fertilizes an egg, forming a zygote, which then develops into an embryo. Over approximately nine months, it undergoes significant changes: forming major organs and systems during the first trimester, growing rapidly and developing features in the second trimester, and preparing for birth in the third trimester. Key milestones include the heartbeat detection, movement felt by the mother, and the baby's ability to survive outside the womb. Understanding these stages helps appreciate the complexity of human development.
