Umbilical artery
Umbilical Artery
The Umbilical Artery (pronounced: um-BIL-i-kal AR-ter-ee) is a significant part of the umbilical cord that carries deoxygenated blood and waste products from the fetus to the placenta during pregnancy.
Etymology
The term "Umbilical" is derived from the Latin word "umbilicus" meaning "navel", and "artery" originates from the Greek word "arteria", meaning "windpipe, artery".
Function
The Umbilical Artery has a crucial role in fetal development. It carries deoxygenated blood and waste products from the fetus to the placenta. This process allows the fetus to eliminate waste and receive oxygen and nutrients from the mother through the umbilical vein.
Anatomy
There are typically two Umbilical Arteries present in the umbilical cord, which coil around the single umbilical vein. These arteries originate from the internal iliac arteries of the fetus.
