Blood circulation in the fetus and newborn how does the fetal circulatory system work during pregnancy, the unborn baby (fetus) depends on its mother for nourishment and oxygen. During pregnancy, the fetal lungs are not used for breathing—the placenta does the work of exchanging oxygen and carbon dioxide through the mother's circulation with the first breaths of air the baby takes at birth, the fetal circulation changes.
This feature is not available right now please try again later. At birth, major changes take place the umbilical cord is clamped and the baby no longer receives oxygen and nutrients from the mother with the first breaths of air, the lungs begin to expand, and the ductus arteriosus and the foramen ovale both close the baby's circulation and blood flow through the heart now function like an adult's. Watch how the blood flows through the fetal circulation and compare it to what happens in the baby's body rishi is a pediatric infectious disease physician and works at khan academy.
Fetal circulation the circulation of blood from the placenta to and through the fetus and back to the placenta fetal circulation can be traced as follows: the oxygenated blood is carried from the placenta to the fetus via the umbilical vein. The fetal circulatory system uses two right to left shunts, which are small passages that direct blood that needs to be oxygenated the purpose of these shunts is to bypass certain body parts – in particular, the lungs and liver – that are not fully developed while the fetus is still in the womb.

Relaxation of the uterine musculature leads to a decrease in umbilical vein pressure and blood deriving from the fetal circulation and from the hepatic vein flows into the inferior vena cava and thereby into the right atrium.

Fetal circulation the blood that flows through the fetus is actually more complicated than after the baby is born ( normal heart ) this is because the mother (the placenta) is doing the work that the baby’s lungs will do after birth. In the placenta the blood becomes enriched with nutrients and oxygen and gets via the unpaired umbilical vein into the fetal blood circulation system more info due to the higher pressure of the blood in the inferior vena cava, more blood flows from it directly into the left atrium via the foramen ovale.
