siemenkalvojen

Siemenkalvot, often referred to as fetal membranes, are essential structures that develop during pregnancy to support and protect the growing fetus. These membranes comprise several layers, the most prominent being the amnion and the chorion. The amnion is the innermost membrane, forming a sac filled with amniotic fluid. This fluid plays a crucial role in cushioning the fetus from external shocks, maintaining a stable temperature, and allowing for fetal movement, which is vital for proper musculoskeletal development.

The chorion is the outermost fetal membrane. In early pregnancy, the chorion contributes to the formation of the placenta, a vital organ responsible for nutrient and oxygen transfer from the mother to the fetus, and waste removal. The amniotic sac, formed by the amnion and chorion, encloses the fetus and amniotic fluid. These membranes are typically expelled from the uterus after childbirth, a process known as the delivery of the afterbirth. In some medical contexts, "siemenkalvot" might also refer to the amniotic sac itself or its components collectively, highlighting their collective role in fetal development and gestation.
