Quizplus · Accepted Answer

The most critical adjustment of a newborn at birth is the establishment of respirations.The cardiovascular system changes markedly after birth as a result of fetal respiration,which reduces pulmonary vascular resistance to the pulmonary blood flow and initiates a chain of cardiac changes that support the cardiovascular system.The infant relies on passive immunity received from the mother for the first 3 months of life.After the establishment of respirations,heat regulation is critical to newborn survival.
