Fetal Circulation Cardiovascular System

Fetal Circulation Pdf Fetus Atrium Heart This intricate system allows the fetus to receive oxygenated blood and nutrients from the placenta. it is comprised of the blood vessels in the placenta and the umbilical cord, which contains two umbilical arteries and one umbilical vein. Once the cardiovascular system is fully established, blood circulation commences and the embryo can directly derive nutrients from its own blood supply. this article will cover the anatomy, structure and function of the fetal circulation.

Fetal Circulation Pdf Fetus Atrium Heart The oxygen rich blood that enters the fetus passes through the fetal liver and enters the right side of the heart. blood coming back from the fetus also enters the right atrium through the superior vena cava and coronary arteries. Through the blood vessels in the umbilical cord, the fetus gets all needed nutrition and oxygen. the fetus gets life support from the mother through the placenta. Fetal circulation refers to the unique circulatory system in fetuses, characterized by low pulmonary blood flow and high systemic blood flow, allowing for preferential oxygenated blood flow to the heart and brain. In utero the systemic vascular system has high blood flow low resistance, the pulmonary vascular system low blood flow high resistance. fetal circulation differs greatly from postnatal circulation as it contains structures that are not required in extrauterine life.

Fetal circulation begins at the placenta, a joint project between the mother and child. the umbilical vein carries oxygen rich, nutrient rich blood from the placenta to the fetal inferior vena cava, joining the vena cava near the liver. this connection is called the ductus venosus. Waste products and carbon dioxide from the fetus are sent back through the umbilical cord and placenta to the mother's circulation to be eliminated. the fetal circulatory system uses two right to left shunts, which are small passages that direct blood that needs to be oxygenated. Thus, the fetal circulation can be defined as a ‘shunt dependent’ circulation. in the fetus, deoxygenated blood arrives at the placenta via the umbilical arteries and is returned to the fetus in the umbilical vein. During pregnancy, the fetal circulatory system works in a different way than after birth. learn about this system and how it changes once a baby is born.
