How is the placenta adapted to its job?

The placenta is adapted to its role by having a large surface area, which enhances nutrient and gas exchange between the mother and the fetus. Its structure includes specialized trophoblast cells that facilitate implantation and create a barrier that protects the fetus while allowing the transfer of essential substances. Additionally, the placenta produces hormones that support pregnancy and regulate maternal physiology, ensuring a stable environment for fetal development. These adaptations collectively optimize the supply of oxygen and nutrients while removing waste products.
