What are the abnormalities of the umbilical cord?
Fetal anomalies most commonly associated with single umbilical artery include several anomalies like ventricular septal defects, hydronephrosis, cleft lip, ventral wall defects, esophageal atresia, spina bifida, hydrocephaly, holoprosencephaly, diaphragmatic hernia, cystic hygromas, and polydactyly or syndactyly.
What organ does the umbilical vein lead to?
the placenta
The umbilical vein, along with the rest of the umbilical cord, leads to the placenta. The placenta gets oxygen, water and nutrients from the mother’s bloodstream because these materials diffuse across the placental barrier. The umbilical vein picks up oxygenated blood from the placenta and carries it back to the fetus.

Umbilical cord problems can cause birth asphyxia (dangerous oxygen deprivation), which can in turn lead to birth injuries such as hypoxic-ischemic encephalopathy (HIE) and cerebral palsy.
What is the function of the umbilical vein?
The umbilical vein carries oxygenated, nutrient-rich blood from the placenta to the fetus, and the umbilical arteries carry deoxygenated, nutrient-depleted blood from the fetus to the placenta (Figure 2.2).
