Study Notes
Pregnancy and Infancy Nutrition
- Full-term pregnancy lasts 39-40 weeks, divided into three trimesters.
- Prenatal development: Embryo (weeks 3-8) followed by Fetus (weeks 9-birth).
- Placenta: Crucial for exchanging nutrients, oxygen, and waste products via the umbilical cord. It also releases pregnancy-supporting hormones and acts as a barrier against some substances (e.g., red blood cells, bacteria, large proteins), while allowing others (e.g., alcohol, drugs) to pass.
