The inferior vena cava IVC is the largest vein in the body, draining blood from the abdomen, pelvis and lower extremities. This pictorial review summarises normal anatomy and embryological development of the IVC.

Cava inferior

The inferior vena cava is a large vein that carries the deoxygenated blood from the lower and middle body into the right atrium of the heart. It is formed by the joining of the right and the left common iliac veins , usually at the level of the fifth lumbar vertebra. The inferior vena cava is the lower " inferior " of the two venae cavae , the two large veins that carry deoxygenated blood from the body to the right atrium of the heart: the inferior vena cava carries blood from the lower half of the body whilst the superior vena cava carries blood from the upper half of the body. Together, the venae cavae in addition to the coronary sinus , which carries blood from the muscle of the heart itself form the venous counterparts of the aorta. It is a large retroperitoneal vein that lies posterior to the abdominal cavity and runs along the right side of the vertebral column. The name derives from Latin : vena, "vein", cavus, "hollow". The IVC is formed by the joining of the left and right common iliac veins and brings collected blood into the right atrium of the heart. The inferior vena cava begins as the left and right common iliac veins behind the abdomen unite, at about the level of L5. Because the inferior vena cava is located to the right of the midline, drainage of the tributaries is not always symmetrical. On the right, the gonadal veins and suprarenal veins drain into the inferior vena cava directly.

The inferior vena cava is also referred to as the posterior vena cava. Deoxygenated blood means most of the oxygen has been removed by tissues, and therefore the blood is darker. The inferior vena cava empties into the right atrium of the heart. The right atrium is located on the right back side of the heart. The inferior vena cava runs posterior, or behind, the abdominal cavity. This vein also runs alongside the right vertebral column of the spine. The inferior vena cava is the result of two major leg veins coming together. These leg veins are called iliac veins. The iliac veins come together at the small of the back, at the fifth lumbar vertebra. Once the iliac veins have merged, they form the inferior vena cava, which transports the deoxygenated blood to the heart.

Cava inferior

Responsible for carrying lower body blood back to the heart. The inferior vena cava also known as IVC or the posterior vena cava is a large vein that carries blood from the torso and lower body to the right side of the heart. From there the blood is pumped to the lungs to get oxygen before going to the left side of the heart to be pumped back out to the body. The IVC gets its name from its structure and location. It is the lower, or inferior, part of the vena cava, which transports blood back to the right side of the heart. The IVC carries blood from the lower body while another vein, known as the superior vena cava , returns blood from the upper half of the body to the heart. The IVC is formed by the merging of the right and left common iliac veins. These veins come together in the abdomen, carrying blood from the lower limbs. The IVC goes from the diaphragm into the right side of the heart, beneath the entrance of the superior vena cava. A few veins merge and drain into the IVC before it makes its way up to the heart:.

The inferior vena cava IVC plural: inferior venae cavae is one of the great vessels that drains venous blood from the lower limbs , pelvis and abdomen into the right atrium of the heart. The inferior vena cava is formed by the confluence of the two common iliac veins at the L5 vertebral level.
