Fetal Circulation

What is the Fetal Circulation?

Fetal circulation is the circulatory system unique to developing fetuses, allowing them to receive oxygenated blood and nutrients from the placenta.

What are the Three Main Shunts of Fetal Circulation?

The three main shunts of fetal circulation are the ductus arteriosus, ductus venosus, and foramen ovale.

Which of the Following is a Structure of Fetal Circulation?

The umbilical vein, ductus arteriosus, and foramen ovale are structures of fetal circulation.

What are the Fetal Circulation Steps?

Fetal circulation steps involve oxygenated blood entering through the umbilical vein, bypassing the liver via the ductus venosus, and mixing in the heart before distribution.

Fetal Circulation Meaning

Fetal circulation refers to the specialized circulatory system present in developing fetuses during pregnancy. Unlike adult circulation, fetal circulation is adapted to meet the unique physiological needs of the developing fetus. Oxygen and nutrients are supplied to the fetus via the placenta through the umbilical cord. Waste products are removed from the fetus and transported back to the placenta for disposal. This fetal circulation system ensures the proper development and growth of the fetus within the womb....

How Does the Fetal Circulation System Work?

The fetal circulation system is different from adult circulation. This complex system allows the fetus to receive oxygenated blood and nutrients from the placenta. It is composed of the blood vessels in the placenta and the umbilical cord, which contains two umbilical arteries and one umbilical vein. Fetal circulation bypasses the lungs via a shunt known as the ductus arteriosus; the liver is also bypassed via the ductus venosus and blood can travel from the right atrium to the left atrium via the foramen ovale....

Conclusion – Fetal Circulation

Understanding fetal circulation is vital for learning the complicated process by which oxygen and nutrients are supplied to the developing fetus while waste products are efficiently removed. Fetal circulation ensures optimal growth and development within the womb. By bypassing the lungs and liver, and utilizing shunts like the ductus arteriosus and ductus venosus, fetal circulation prioritizes oxygenation and nutrient delivery to vital organs....
