During a prenatal visit, what is included in the description of fetal circulation?

Fetal circulation is characterized by the presence of two umbilical arteries and one umbilical vein. This configuration is crucial because it supports the developing fetus by facilitating the exchange of oxygen and nutrients. The two umbilical arteries transport deoxygenated blood from the fetus back to the placenta, where waste products and carbon dioxide are exchanged for oxygen and nutrients. The one umbilical vein carries the oxygenated blood from the placenta back to the fetus, making it essential for fetal development.

Understanding this arrangement is vital for recognizing how blood is circulated and exchanged during pregnancy. Any deviations from this norm could indicate potential cardiovascular issues in the fetus.
