Fetal circulation The fetel circulation is the circulatory system of a human fetus, often encompassing the entire fetoplacental circulation which includes the umbilical cord and the blood vessels within the placenta that carry fetal blood.
Umbilical cord 2 umbilical arteries – Return non oxygenated blood, fecal waste to placenta. 1umblical vein – Brings oxygenated blood and nutrients to the fetus.
Three shunt are present in fetal life - Ductus venosus connects the umbilical vein to the inferior vena cava. Ductus Arterious connect the main pulmonary artery to the arota. Foramen ovale Anatomical opening between the right and left atrium.
Flow chart of fetus circulation Oxygenated blood from mother ( via the umbilical vein) Liver( fetus) Recives deoxygenated blood from the portal vein through the ductus venosus. Inferior vena cava (mixed with deoxygenated blood)
5.Right atrium 6.Left atrium ( through foraman ovale) 7.Left ventricle 8.Brain and heart ( through arota)
Deoxygenated blood Inferior vena cava and. Superior vena cava Right atrium Right ventricle Pulmon Inferior vena cava and. Superior vena cava ary artery Descending aorta ( through ductus Arterious)
Change in the fetal circulation after birth- Umbilical arteries - umblical ligament Umblical vein – ligament teres
Key points Fetal circulation Bypass the lungs via a shunt known as the ductus Arterious. The liver is also bypassed via the ductus venosus Blood can travel from the atrium to the left atrium via the foraman ovel Normal fetal heart rate 110 to 160 b/min.
