Umbilical artery
Umbilical Artery
The Umbilical Artery is a major blood vessel present in the umbilical cord that carries deoxygenated blood from the fetus to the placenta in mammals, including humans.
Structure[edit | edit source]
The umbilical artery is a paired structure, with two arteries coiling around a single umbilical vein. The arteries carry deoxygenated blood and waste products from the fetus to the placenta. The umbilical arteries are remnants of the fetal mesonephric ducts.
Function[edit | edit source]
The primary function of the umbilical artery is to carry deoxygenated, nutrient-depleted blood from the fetus to the placenta. This allows for the exchange of nutrients and oxygen from the mother to the fetus, and the removal of waste products from the fetus to the mother.
Clinical significance[edit | edit source]
Abnormalities in the umbilical artery, such as a single umbilical artery (SUA), can be a sign of potential genetic abnormalities or fetal health issues. SUA is often detected during routine ultrasound examinations.
