Trophoblastic tissue is the outer layer of cells surrounding the embryo and is critical for the formation of the placenta.
Trophoblast: The Placenta's Precursor
The trophoblast plays a vital role in early embryonic development. Here's a breakdown of its key features:
- Location: The outermost layer of cells surrounding the embryo.
- Structure: Characterized by numerous small projections called chorionic villi. These villi grow into the lining of the uterus.
- Function: It's the foundational tissue that develops into the placenta and the membranes enclosing the embryo. The placenta facilitates nutrient exchange, waste removal, and gas exchange between the mother and the developing fetus.
In essence, trophoblastic tissue is the precursor to the placenta, the vital organ supporting the developing embryo during pregnancy.
