During pregnancy, the unborn baby (fetus) depends on its mother for nourishment and oxygen. Since the fetus doesn’t breathe air, his or her blood circulates differently than it does after birth: 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. The baby's circulation and blood flow through the heart now function like an adult's.

KEY WORDS: circulation; blood flow; vein; artery; shunt; fetus. INTRODUCTION. Modern techniques, particularly ultrasound with its. Doppler modalities, have  Neonates may revert to a persistent fetal circulation (PFC) with decreased pulmonary blood flow and a right to left shunt in response to certain stimuli such as  19 Oct 2012 spetal defect, atria, blood pressure are main topics here.

Anatomy and Physiology Fetus depends on placenta to meet O2 needs while organs continue formation Oxygenated blood flows from the placenta to the fetus via the umbilical vein 6. After reaching fetus theblood flows through theinferior vena cava FETAL CIRCULATION How does blood flow through the heart and lungs? In fetal circulation The shunt that bypass the lungs is called the foramen ovale. It moves blood from the right atrium of the heart to the left atrium. The ductus arteriosus moves blood from the pulmonary artery Fetal circulation is significantly different from that of a newborn (Fig. 37.4). 15 Oxygen-rich blood from the placenta passes through the umbilical vein directly to the fetal liver, where the circulation splits and flows into both the ductus venosus (20%–30% of flow) and portal sinus circulation. It then passes into the inferior vena cava and enters the right atrium. Fetal Blood: Circulation Diagram & Concept. there is a small amount of blood flow to these two places. A small amount of blood entering the right atrium does not go through the left atrium

valves (pulmonary and semilunar) allow blood to flow only from the ventricles out of the heart the fetal heart, blood arriving to the right side of the heart is passed through The endocardium is a sheet of epithelium called endothelium that 

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. Fetal Hemoglobin (HbF)! Higher O2 affinity than adult Hemoglobin allows HbF to ÒsuckÓ oxygen across the placenta into fetal circulation.! After birth, RBCs are killed off and replaced with RBCs containing normal adult Hb.! Rapid death of RBCs in first weeks of life leads to neonatal jaundice" Normal up to 1-2 weeks" Jaundice after 2 weeks is Physiology of Fetal Circulation G.

Prevents mixing with desaturated blood in portal circulation. Has sphincter mechanism: Closes and prevents overloading of heart during uterine contraction. Functional: With umbilical cord clamping, venous return in the IVC decreases and reduction of flow through ductus venosus allows passive collapse.

Home Fetal Circulation Circulation of Baby after Birth How are gases exchanged? The two arteries contained in the umbilical cord remove the deoxygenated blood while the vein contained in the umbilical cord sends oxygenated blood to the fetus The exchange of gases occur through the surfaces of the numerous alveoli inside the lungs to permit the diffusion of oxygen and carbon dioxide. Frequently, fetal growth restriction is a consequence of impaired placental perfusion or placental insufficiency. 10 In response to general fetal malnutrition due to placental insufficiency or other factors such as smoking or maternal nutrient restriction, blood flow is preferential to the brain and heart, which deprives other organs of adequate oxygen and an adequate supply of nutrients.

Fetal blood vessels and fetal circulation. Once the main arteries and veins as well as the heart are developed, usually after the 8th week of fetal development, deoxygenated blood is returned from the fetal systemic circulation to the placenta via two umbilical arteries, which branch off the fetal internal iliac arteries.

29 Oct 2006 Compromise of the fetal blood flow through the umbilical cord B) Diagram of the circulation within the fetus, umbilical cord and placenta. III. 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.
