What is the function of the umbilical cord?
Answers
The umbilical cord contains blood vessels which supply blood between the foetus and the placenta.
Explanation:
The umbilical cord forms around the fifth week of pregnancy and can grow up to 20 inches long at full-term. It is a tough, sinewy structure with two main layers: an outer layer of smooth muscle, and an inner layer containing a gelatinous fluid called Wharton's jelly. There are typically three vessels within this substance: one vein and two arteries. The vein carries oxygen and nutrient-rich blood from the placenta to the fetus, and the arteries carry deoxygenated and nutrient-depleted blood away from the fetus.

These two branches form a circuit in the fetus's body and reconnect to the umbilical cord outside. In rare cases, the umbilical cord may not develop correctly, or some other problem occurs during birth. Sometimes these problems can be detected via ultrasound before birth, but in many cases, they are not noticed until after the baby is born. Let's look at some of these potential issues and how they can affect the baby.
