The vena cava are two sets of veins: the superior vena cava, and the inferior vena cava. The inferior vena cava is the longest vein in the body.
The superior vena cava mainly (by volume) brings deoxygenated blood from regions of the body above/at the level of the heart & the arms. The azygous vein anastomoses with the superior vena cava, and thus the superior vena cava receives blood from both sides of the posterior wall of the thorax, via the azygous vein and hemiazygous vein.
In some individuals anastomoses may occur between the azygous & hemiazyous vein with the right & left renal veins, respectively, and/or the inferor vena cava. Therefore blood returning to the heart via the abdomen or kidneys may also pass through the superior vana cava to the heart. The inferor vena cava returns blood, mainly from the level below the diaphragm down to the feet, to the heart.
postcava - inferior vena cava precava - superior vena cava
Yes. it has an inferior vena cava
The inferior vena cava
Either through the Superior Vena Cava located at the superior aspect of the heart, through the Coronary Sinus located at the inferior aspect of the heart, or through the Inferior Vena Cava located at the inferior aspect of the heart. All of these drain into the right atrium.
The vena cavae, which returns blood from the bottom half of your body back to your heart.
superior vena cava
The superior vena cava, inferior vena cava, and coronary sinus are three vessels that drain into the right atrium of the heart.
The inferior vena cava is the largest vein, and connects to the right atrium of the heart. The other large vein is the superior vena cava, which receives blood from the upper half of the body.
An inferior vena cava diameter > 12 mm
Inferior vena cava
the inferior vena cava caries de-oxygenated blood.
The inferior vena cava is the major vein which carries the blood into the heart from the lower half of the body.
