Trophoblast villi are specialized structures within the placenta essential for fetal development, formed by the trophoblast cells.
Understanding Trophoblast Villi
Trophoblast villi facilitate the exchange of nutrients and waste between the mother and the fetus. The reference states that trophoblasts are specialized cells of the placenta that play an important role in embryo implantation and interaction with the decidualized maternal uterus. These villi are finger-like projections that increase the surface area available for this exchange. The core of these villi contains:
- Mesenchymal cells
- Placental blood vessels, which are directly connected to the fetus' circulation via the umbilical cord.
This direct connection ensures efficient transport of oxygen, nutrients, and other essential substances from the mother's blood to the fetus, while simultaneously removing waste products from the fetal circulation. This intricate structure and function are crucial for healthy fetal growth and development.
