Chapter 20, Problem 20.5.2AYLO
Summary Introduction
To analyze:
The two subunits in and near the fetal heart that enable most blood to bypass the non-functional lungs.
Introduction:
In the fetus, the lungs are not yet inflated or functional. So, there is a little point for pumping all the blood through the lungs of the fetus. There, the lungs receive enough blood to meet the
