Vena cava

Vena Cava

The Vena Cava is a large vein that carries deoxygenated blood from the body back to the heart. There are two types of vena cava: the Superior vena cava and the Inferior vena cava.

Superior Vena Cava

The Superior vena cava is the second largest vein in the human body. It carries blood from the upper half of the body back to the heart. It is formed by the left and right brachiocephalic veins, which receive blood from the upper limbs and the head and neck.

Inferior Vena Cava

The Inferior vena cava is the largest vein in the human body. It carries blood from the lower half of the body back to the heart. It is formed by the union of the left and right common iliac veins, which receive blood from the lower limbs and the pelvis and abdomen.

Clinical Significance

The vena cava can be affected by a number of conditions, including Deep vein thrombosis, Vena cava syndrome, and Vena cava filter. These conditions can lead to serious complications, such as pulmonary embolism, if not treated promptly.
