🤰🧬 ## The Journey from Zygote to Baby 👶 ### Early Developmental Stages 🌱 - Humans start as a tiny cell (2mm) and grow to be ~850 times larger - Key developmental instructions: Divide, Differentiate, Develop - Stages of early cell development: - Cleavage phase: Cells split rapidly - Morula stage: Berry-shaped cell cluster - Blastocyst stage: Hollow sphere with inner cell mass ### Implantation and Hormonal Control 🔬 - Blastocyst travels to uterus and implants in endometrium - Hormones play a crucial role, especially: - Human Chorionic Gonadotropin (hCG) - Estrogen - Progesterone ### Placenta Formation 🌈 - A unique temporary organ formed from maternal and embryonic tissues - Transfers nutrients, hormones, and waste between mother and baby ### Maternal Body Changes 🤯 Incredible physiological transformations include: - 40% increase in blood volume - Uterus expansion - Breast changes - Hormonal shifts - Joint loosening - Increased metabolism ### Labor and Delivery 🏥 - Triggered by hormonal changes - Stages include: 1. Cervical dilation 2. Pushing 3. Placenta delivery ### Key Takeaway 💖 Pregnancy is a complex, hormonally-driven process of creating new human life!
