MV Fetus Medical Human 3D Cross Section
A human fetus is the developing offspring in the womb, specifically from the ninth week of pregnancy until birth. This stage follows the embryonic phase, where the basic structures and organs begin to form.
Key Stages of Fetal Development:
- Fetal Stage: Begins at approximately 9 weeks after fertilization. The fetus undergoes significant growth and development, including the formation of organs and systems.
- Growth: By the end of the first trimester (around 12 weeks), the fetus is about 3 inches long and has distinct features like fingers and toes.
- Development: Throughout the second and third trimesters, the fetus continues to grow, with rapid development of the brain, lungs, and other vital organs.
Important Aspects:
- Nutrition: The fetus receives nutrients and oxygen through the placenta, which is crucial for its growth and development.
- Movement: Fetal movements can typically be felt by the mother around 18-25 weeks of pregnancy.
