La vena cava inferior se origina de la unión de las dos venas ilíacas primitivas sobre el cuerpo vertebral de la 5ª vértebra lumbar (L5). The main difference between superior and inferior vena cava is that the superior vena cava drains blood from the upper part of the body while the inferior vena cava drains blood from the lower part of the body. Die Vena cava superior ist eine der größten Venen des menschlichen Körpers. The heart beats to force the blood through the lungs for oxygenation so it can be returned to circulation to bring fresh oxygen and nutrients to the cells. The inferior vena cava is also referred to as the posterior vena cava. Its walls are rigid and it has valves so the blood does not flow down via gravity . From the pelvis, the inferior vena cava ascends through the posterior abdominal body wall just to the right of the vertebral column. The anterior vena cava is a blood vessel responsible for conducting deoxygenated blood from the upper part of the body to the right atrium of the heart. ve´nae) (L.) vein (see also Appendix 2-6). Furthermore, superior vena cava drains blood from the head, neck, arms, and the upper chest wall while inferior vena cava drains blood from the legs, pelvis, and abdomen. 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. It is formed by the joining of the right and the left common iliac veins , usually at the level of the fifth lumbar vertebra . Trayecto.

It arises from the union of the left and right brachiocephalic veins, posterior to the first right costal cartilage.It descends vertically through the superior mediastinum, behind the intercostal spaces and to the right of the aorta and trachea. 2 Anatomie. The inferior vena cava (or IVC) is a large vein that carries the deoxygenated blood from the lower and middle body into the right atrium of the heart . See Appendix 2-6. inferior vena cava the venous trunk for the lower extremities and the pelvic and abdominal viscera; it empties into the right atrium of the heart. The superior vena cava is classified as a large vein, with a wide diameter of up to 2cm and a length of approximately 7cm.. 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. Anatomical Position. vena ca´va the inferior vena cava and superior vena cava considered as a unit. Die kurze, aber großlumige Vena cava superior entsteht aus dem Zusammenfluss der rechten und linken Vena brachiocephalica in Höhe der ersten Rippe. Sie zieht von dort aus im Mediastinum entlang der medialen Seite der rechten Pleurahöhle nach kaudal. vena [ve´nah] (pl. The inferior vena cava forms at the superior end of the pelvic cavity when the common iliac veins unite to form a larger vein. The inferior vena cava is a large vein that carries deoxygenated blood from the lower body to the heart.
