Throughout the course of pregnancy, the umbilical cord serves as a vital connection between the mother and her baby. Specifically, it acts as a lifeline, linking the baby to the placenta and facilitating the provision of essential oxygen and nourishment required for the baby’s development during the entire gestation period of nine months.
Anatomy of the Umbilical Cord
The umbilical cord initially consists of two arteries and two veins. However, as it develops further, one of the veins typically degenerates, resulting in a three-vessel cord. This means that there is one vein responsible for transporting oxygenated blood from the placenta to the fetus, while the two arteries carry blood from the fetus back to the placenta.
Mobility
The umbilical cord not only provides oxygen and nutrients to the fetus but also plays a crucial role in facilitating movement within the womb. Designed to be both sturdy and flexible, it supports the development of the fetus’s neuromotor skills. Forming around the fourth week of pregnancy, the umbilical cord gradually grows to approximately 22 inches [https] as the pregnancy progresses.
