Femoral vein
Femoral Vein
The Femoral Vein (pronounced: fuh-MOR-uhl vayn) is a significant blood vessel located in the upper thigh and pelvic region of the human body. It plays a crucial role in the circulatory system, carrying deoxygenated blood from the lower extremity back to the heart.
Etymology
The term "Femoral" is derived from the Latin word "femur," which means thigh. The word "vein" comes from the Old French "veine," which has its roots in the Latin "vena," meaning blood vessel.
Anatomy
The Femoral Vein runs parallel to the Femoral Artery, and together they form the Femoral Sheath, a fibrous covering in the upper thigh. The vein begins at the adductor canal, a passageway in the thigh, and ends at the lower edge of the Inguinal Ligament, where it becomes the External Iliac Vein.
Function
The primary function of the Femoral Vein is to return deoxygenated blood from the lower extremity to the heart. It does this by transporting blood upwards from the Popliteal Vein (located behind the knee) and other smaller veins in the leg.
