What is the role of the amniotic sac and its histology?
The amniotic sac surrounds the developing fetus and is composed of two membranes: the amnion and the chorion. The amnion is the innermost layer and consists of a single layer of epithelial cells, while the chorion is the outer layer containing trophoblast cells. The amniotic sac provides a protective environment, cushioning the fetus and maintaining a stable temperature.
