The flexible cord connecting the fetus and the placenta, containing the umbilical blood vessels, and that carries nutrients to the fetus and waste from the fetus through the placental wall.
A cord containing two arteries and one vein which links the fetus inside the uterus to the placenta.
Connection between the developing fetus and the placenta.
The hollow, ropelike structure, roughly 1½ to 2 feet long, connecting the fetus to the placenta, that develops by about the fifth week of pregnancy. It supplies oxygen and nutrition and takes away waste products by way of two arteries and a vein. During pregnancy, the umbilical cord normally develops numerous twists and turns, even becoming wrapped around the fetus. In some cases this can cause serious problems, as when it becomes wrapped around the fetus’s neck; if that happens during delivery, it can often be slipped free. Sometimes a long cord will slip down (prolapse) into the mother’s cervix during labor; since that can endanger the flow of oxygen-containing blood, causing hypoxia or anoxia, a cesarean section or sometimes a forceps delivery may be indicated. If the umbilical cord has only one artery, instead of two, the fetus may get insufficient oxygen and nutrition, possibly leading to birth defects. Shortly after delivery, the umbilical cord is clamped and then cut to about an inch; within days the stump falls off, the remaining scar being called the navel, umbilicus, or belly button.
Flexible cordlike structure that connects the fetus to the placenta during pregnancy. It contains arteries that carry blood to the placenta and a vein that returns blood to the fetus and the remains of the yolk sac and allantois. In the newborn it is usually about 24 inches (60 centimeters) long.
A vascular structure attaching the fetus to the placenta in utero.
A flexible, ropelike structure that connects the fetus to the placenta inside the uterus during pregnancy. The umbilical cord delivers nutrients from the mother to the fetus and eliminates waste from the fetus. The umbilical cord contains two arteries and one vein and is about i6 to 24 inches long. At birth, the umbilical cord is clamped and cut.
The strand of tissue connecting the fetus to the placenta. It contains two arteries that carry blood to the placenta and one vein that returns it to the fetus. It also contains remnants of the allantois and yolk sac and becomes ensheathed by the amnion.
The fleshy tube containing two arteries and a vein through which the mother supplies the fetus with oxygen and nutrients. The cord, which is up to 60 cm long, ceases to function after birth and is clamped and cut about 2-5 cm from the infant’s abdominal wall. The stump shrivels and falls off within two weeks, leaving a scar which forms the umbilicus.
The attachment connecting the fetus with the placenta. It contains two arteries and one vein surrounded by a gelatinous substance, Wharton’s jelly. The umbilical arteries carry blood from the fetus to the placenta, where nutrients are obtained and carbon dioxide and oxygen are exchanged; this oxygenated blood returns to the fetus through the umbilical vein.
The circulatory channels enabling the developing fetus to obtain nourishment and oxygen from the maternal system, while also facilitating the elimination of the baby’s waste materials, are known as the umbilical blood vessels. One extremity of the umbilical cord is connected to the placenta, while the other extremity is attached to the baby’s umbilicus, or commonly referred to as the belly button.
The umbilical cord is a cord-like structure that links the fetus to the placenta. This vital cord serves to deliver oxygen and nutrients from the mother’s circulation to the fetus. Typically measuring 40–60 cm in length, the umbilical cord comprises a gelatinous substance and contains two arteries along with a vein.
Following childbirth, the umbilical cord is clamped and subsequently severed around 2.5 cm away from the baby’s abdomen. Within a span of a few weeks, the remaining portion detaches, resulting in a scar known as the umbilicus or navel.
In rare instances, the umbilical cord may descend through the mother’s cervix during labor. This scenario poses a significant risk as the cord could become compressed between the mother’s pelvis and the baby’s body, potentially compromising the baby’s oxygen supply. Swift intervention through methods like caesarean section or forceps delivery becomes imperative. Another issue that might arise during childbirth is the cord becoming entangled around the baby’s neck, resulting in strangulation. Usually, this predicament can be resolved by gently slipping the cord over the baby’s head.
On occasion, the umbilical cord may contain only a single artery. This situation could potentially be linked to birth abnormalities.
The cord-like structure that links the fetus to the placenta, through which the mother provides her unborn child with blood, oxygen, and nutrients, and through which waste products from the baby are returned to the mother.
