How does a babys respiration and circulation change whenthe baby is born?

At birth, a baby's respiration and circulation undergo significant changes as they transition from fetal to independent life. The initiation of breathing clears fluid from the lungs, allowing air to fill them and establish normal oxygen exchange. Circulation shifts as the ductus arteriOSus and foramen ovale close, redirecting blood flow to the lungs for oxygenation instead of through the placenta. This transition is crucial for the newborn's adaptation to life outside the womb.
