Quizplus · Accepted Answer

As the baby is in the womb, it receives oxygen through the umbilical cord from the mother's bloodstream, and the carbon dioxide is eliminated through the placenta. After birth, the umbilical cord is cut, and the baby's respiratory system takes over. The respiratory center in the brainstem detects the increasing carbon dioxide level in the blood and triggers the baby's first breath.
