'Placental' refers to anything related to the placenta, an organ that develops in the uterus during pregnancy. It provides oxygen and nutrients to the growing baby and removes waste products. Most mammals, including humans, are placental mammals, meaning they develop inside the mother's uterus with the help of a placenta. The placenta is crucial for fetal development. It acts as a bridge between mother and child. It's a temporary organ, expelled after birth.
