The umbilical cord connects the developing fetus directly to the placenta inside the uterus during pregnancy. The placenta acts as a vital lifeline, managing nutrient uptake, waste elimination, and gas exchange between the mother and the baby. While one end of the flexible cord is securely inserted into the baby's abdomen at the navel, the other end anchors firmly into the maternal-fetal interface of the placenta, ensuring continuous blood and oxygen flow throughout gestation.
