Quizplus · Accepted Answer

Acidosis stimulates the respiratory center in the brainstem, leading to the first breath. As the infant passes through the birth canal, the umbilical cord is compressed, reducing blood flow to the fetus and increasing carbon dioxide levels, which can result in acidosis. This triggers the respiratory center and causes the infant to take its first breath.
