What determines fetal circulation in pregnancy?
During pregnancy, the unborn baby (fetus) depends on its mother for nourishment and oxygen. Since the fetus doesn’t breathe air, their blood circulates differently than it does after birth: The placenta is the organ that develops and implants in the mother’s womb (uterus) during pregnancy.
What is normal fetal circulation?
Fetal circulation bypasses the lungs via a shunt known as the ductus arteriosus; the liver is also bypassed via the ductus venosus and blood can travel from the right atrium to the left atrium via the foramen ovale. Normal fetal heart rate is between 110 and 160 peats per minute.
When does fetal blood circulation begin?
Blood cells and vessel production in structures outside the embryo proper called the yolk sac, chorion, and connecting stalk begin about 15 to 16 days following fertilization. Development of these circulatory elements within the embryo itself begins approximately 2 days later.
