Flow Chart Fetal Circulation

During pregnancy, the circulatory system of a developing fetus undergoes significant changes to ensure proper oxygen and nutrient exchange between the mother and the baby. A flow chart of fetal circulation can help visualize the complex network of blood vessels and pathways involved in this process. Let’s explore the key stages of fetal circulation through a detailed flow chart.

At the beginning of fetal circulation, deoxygenated blood from the fetus is carried through the umbilical arteries to the placenta. In the placenta, oxygen and nutrients are exchanged between the maternal blood in the placental sinusoids and the fetal blood in the chorionic villi. This oxygen-rich blood is then carried back to the fetus through the umbilical vein.

As the blood flows through the umbilical vein, it bypasses the fetal liver through the ductus venosus, which directs a portion of the blood directly to the inferior vena cava. This shunts oxygenated blood away from the liver and towards the fetal heart for distribution to the rest of the body.

2. Circulation in the Fetal Heart

Once the oxygenated blood reaches the fetal heart, it enters the right atrium and is then directed to the left atrium through the foramen ovale, a hole in the interatrial septum. This bypasses the fetal lungs, which are non-functional in utero, allowing the oxygen-rich blood to be pumped out to the body through the aorta.

After circulating through the body, deoxygenated blood returns to the placenta for reoxygenation via the umbilical arteries, completing the cycle of fetal circulation. This intricate network of blood vessels and shunts ensures that the developing fetus receives the oxygen and nutrients necessary for growth and development.

3. Conclusion

Understanding the flow chart of fetal circulation is essential for healthcare professionals and parents alike to appreciate the complexity of the circulatory system during pregnancy. By visualizing the intricate pathways of blood flow in the developing fetus, we can better comprehend the adaptations that occur to support the growing baby until birth.
