Question

Give two characteristics of fetal circulation that lead to the majority of the blood being directed away from the lungs.

Answer 1

Fetal circulation:

1. The circulatory system of the fetus in animals that give birth live is known as fetal circulation.
2. The word usually refers to complete fetal circulation, including the umbilical cord and the blood arteries that convey fetal blood within the placenta.

Characteristics:

The characteristics of fetal circulation that lead to the majority of the blood being directed away from the lungs are as follows:

1. All of the major blood arteries, as well as the heart, are basically developed by the third month of pregnancy.
2. Blood flow is similar to that of an adult in most cases.
3. However, there are certain distinctions between fetal and postnatal circulation.
4. The umbilical veins carry oxygenated blood towards the fetus and into the heart.
5. In the umbilical arteries, deoxygenated blood leaves the fetus.
6. The lungs of a fetus are virtually non-functional.
7. As a result, fetal circulation has a number of traits that route the majority of blood away from the lungs.
