CIRCUMFLEX ILIAC VEIN Meaning and
Definition
-
The circumflex iliac vein is a term used in human anatomy to refer to a vein that is located in the lower abdomen, specifically in the area known as the iliac fossa. It is part of the venous drainage system of this region and plays an important role in the circulation of blood.
The circumflex iliac vein is a tributary of the external iliac vein, one of the major blood vessels in the pelvic region. It arises from the superficial veins of the lower abdomen and travels upwards, parallel to the iliac crest. Along its course, it receives blood from various sources, including the abdominal wall muscles and connective tissue.
The vein has a curved or flexed configuration, hence the term "circumflex," which describes its winding or bending nature. The circumflex iliac vein also exhibits a variable anatomy, meaning its size, course, and connections can differ among individuals. This flexibility of anatomy is important to consider during surgical procedures in the region.
The primary function of the circumflex iliac vein is to drain deoxygenated blood, along with waste products, from the lower abdomen. It then transports this blood to the external iliac vein, which ultimately leads to the inferior vena cava – the largest vein in the body. From the inferior vena cava, the blood is returned to the heart for oxygenation and redistribution throughout the body.
