Explanation When we compared the cardiovascular system with that of fetus the fetal lungs are collapsed and nonfunctional, and the digestive tract has nothing to digest. Instead, diffusion across the placenta provides for the respiratory and nutritional needs of the fetus. This situation changes dramatically at birth, when the newborn's system is separated from that of the mother...
