placentavillierna

Placentavillierna refers to villi of the placenta. These villi are small, finger-like projections that make up the bulk of the placental tissue. They are the primary functional units of the placenta, responsible for the exchange of nutrients, gases, and waste products between the mother and the fetus. The branching structure of the villi significantly increases the surface area available for this exchange. Each villus contains a fetal capillary network surrounded by a layer of specialized cells called trophoblasts. These trophoblasts are crucial for mediating the transport of substances across the placental barrier. During pregnancy, these villi develop and mature, undergoing significant changes in their structure and vascularization to meet the growing demands of the fetus. Their presence is essential for a healthy pregnancy and successful fetal development. If placentavillierna are abnormal in number, size, or structure, it can lead to various pregnancy complications.
