  • Blood Circulation in the Fetus and Newborn - Stanford . . .
    Circulating blood bypasses the lungs and liver by flowing in different pathways and through special openings called shunts Blood flow in the unborn baby follows this pathway: Oxygen and nutrients from the mother's blood are transferred across the placenta to the fetus through the umbilical cord
  • Fetal Circulation - American Heart Association
    After oxygenated blood arrives at the right atrium, it flows through the foramen ovale (an opening between the right and left atrium) to the left ventricle, then into the aorta (the main vessel, which carries blood from the heart to the rest of the body and the brain)
  • Physiology, Fetal Circulation - StatPearls - NCBI Bookshelf
    Fetal circulation undergoes a rapid transition after birth to accommodate extra-uterine life Human understanding of fetal circulation originated from fetal sheep, but ultrasound and magnetic resonance imaging (MRI) during the fetal period now provide detailed information [2]
  • Fetal circulation: Circulation of blood in the fetus | Kenhub
    Once it closes during fetal life, it becomes the ligamentum arteriosum Patent ductus arteriosus - During gestation, the fetal lungs are not inflating and therefore are not oxygenating the blood The fetus is entirely dependent on the placenta for oxygenated blood (via the umbilical vein)
  • Fetal blood and circulation, Changes of fetal circulation . . .
    The ductus arteriosus, which connects the pulmonary trunk to the systemic circulation, closes off within 1-2 days after birth Once closed, the ductus arteriosus is replaced by connective tissue and is known as the ligamentum arteriosum
  • Fetal Physiology and the Transition to Extrauterine Life
    The accumulation of fetal lung fluid within the fetal airways is critical for fetal lung development The transition to extrauterine life is characterized by changes in circulatory pathways, initiation of ventilation and oxygenation via the lungs, and many changes in metabolism
  • Blood Circulation in the Fetus and Newborn | Childrens . . .
    How does the fetal circulatory system work? During pregnancy, the fetal circulatory system works differently than after birth: The fetus is connected by the umbilical cord to the placenta, the organ that develops and implants in the mother's uterus during pregnancy
