What is the physiological benefit of incorporating shunts into the fetal circulatory system?
What will be an ideal response?
Answer: Circulatory shunts bypass the fetal lungs and liver, bestowing them with just enough oxygenated blood to fulfill their metabolic requirements. Because these organs are only semifunctional in the fetus, it is more efficient to bypass them and divert oxygen and nutrients to the organs that need it more.
