External iliac vein
External Iliac Vein
The External Iliac Vein (Pronunciation: Ex-ter-nal Il-i-ac Vein) is a significant structure in the human anatomy that plays a crucial role in the circulatory system.
Etymology
The term "External Iliac Vein" is derived from the Latin words "externus" meaning "outside", "iliacus" referring to the "hip", and "vena" meaning "vein".
Definition
The External Iliac Vein is a large vein located in the pelvic region. It is formed by the union of the femoral vein and the deep circumflex iliac vein. The vein runs along the brim of the pelvis and joins with the internal iliac vein to form the common iliac vein.
Function
The primary function of the External Iliac Vein is to carry deoxygenated blood from the lower extremities back to the heart. It serves as a conduit between the femoral vein and the common iliac vein, facilitating the return of blood from the legs and lower torso to the heart for oxygenation.
