placentától
The placenta is a temporary organ that develops in the uterus during pregnancy. It provides oxygen and nutrients to the growing baby and removes waste products from the baby's blood. The placenta is connected to the baby by the umbilical cord. It is typically disc-shaped and weighs about one pound at full term. The placenta is composed of tissues from both the mother and the fetus. It plays a crucial role in maintaining the pregnancy and supporting fetal development. After birth, the placenta is expelled from the uterus, a process known as the afterbirth. In some cultures, the placenta is buried or consumed for its perceived health benefits, though scientific evidence for these practices is limited. The study of the placenta is called placentology.
