The umbilical cord is a narrow tube-like structure that connects the developing
baby to the placenta
. The cord is sometimes called the baby's “supply line” because it carries the baby's blood back and forth, between the baby and the placenta.
What are the two ends of the umbilical cord attached to?

Where does the umbilical cord attach too?
The umbilical cord connects
to the baby's abdomen from the placenta
, which in turn is connected to the mother's uterus. The placenta is responsible for producing pregnancy hormones, as well as hosting important nutritional exchanges between the mother and baby's blood supply.
When does umbilical cord attach?
Umbilical cord development begins in the embryologic period
around week 3
with the formation of the connecting stalk. By week 7, the umbilical cord has fully formed, composed of the connecting stalk, vitelline duct, and umbilical vessels surrounding the amniotic membrane.
Is the umbilical cord attached to the amniotic sac?
What Does the Umbilical Cord Do? The umbilical cord carries life-giving blood to a baby while it grows inside the mother's womb. The
cord attaches from the baby's stomach to the placenta
, a disc-shaped organ in the mother's uterus wall.
Do babies in the womb poop?
During the many months that your baby grows in the womb, they'll take in nutrients and expel wastes. But in most cases, this waste
is not in the form of feces
. When your baby poops for the first time, they emit a waste called meconium. This usually happens after birth — sometimes almost immediately after!
What happens when a baby's cord is around the neck?
If the cord is looped around the neck or another body part,
blood flow through the entangled cord may be decreased during contractions
. This can cause the baby's heart rate to fall during contractions. Prior to delivery, if blood flow is completely cut off, a stillbirth can occur.
Is velamentous cord insertion considered high risk?
Typically, marginal cord insertion has little negative effect. However, there is
a high risk of hemorrhage, or blood loss
, for infants with velamentous cord insertion because the umbilical blood vessels are unprotected by umbilical tissue.
What happens if the umbilical cord is on the side of the placenta?
A velamentous cord insertion
is when a fetus' umbilical cord abnormally inserts on the edge of the placenta along the chorioamniotic membranes, causing fetal blood vessels to travel unprotected from the placenta until they come together and reach the protection of the umbilical cord.
What happens to umbilical cord if not cut?
“It's not some kind of waste material the body produces separately.” When the umbilical cord is not cut,
it naturally seals off after about an hour after birth
. The umbilical cord and attached placenta will fully detach from the baby anywhere from two to 10 days after the birth.
Can the baby pull the umbilical cord?
DO NOT try to pull it off
, even if it is only hanging on by a thread. Watch the umbilical cord stump for infection. This does not occur often. But if it does, the infection can spread quickly.
What week does the baby start eating from umbilical cord?
Over the course of your pregnancy, the placenta grows from a few cells into an organ that will eventually weigh about 1 pound. By
week 12
, the placenta is formed and ready to take over nourishment for the baby.
Is it common for umbilical cord to wrap around?
A nuchal cord
is a complication that occurs when the umbilical cord wraps around the baby's neck one or more times. This is common and occurs in about 15 to 35 percent of pregnancies.
Can I hurt my baby by pressing on my stomach?
Not much can beat the feeling of a toddler running to you for a big hug. And, for most patients, the force of a
20- to 40-pound child bumping your belly is not enough to harm the baby
.
Small blood vessels carrying the fetal blood
run through the placenta
, which is full of maternal blood. Nutrients and oxygen from the mother's blood are transferred to the fetal blood, while waste products are transferred from the fetal blood to the maternal blood, without the two blood supplies mixing.
What are the risks of marginal cord insertion?
Complications from Marginal Cord Insertion
Marginal cord insertion
can restrict or reduce the blood flow and circulation to the fetus during pregnancy
. Reduced fetal blood flow can cause intrauterine growth restriction (IUGR) and other developmental abnormalities in the fetus.
