Detailed explanation-1: -The right and left brachiocephalic veins, also known as the innominate veins, join to form the superior vena cava posterior to the inferior border of the first right costal cartilage. These veins carry blood from the chest wall, esophagus, lungs, neck, and pericardium.

Detailed explanation-2: -A large vein that carries blood to the heart from other areas of the body. The vena cava has two parts: the superior vena cava and the inferior vena cava. The superior vena cava carries blood from the head, neck, arms, and chest.

Detailed explanation-3: -What is the vena cava? The superior vena cava and inferior vena cava are very large veins that bring deoxygenated blood to your heart to get oxygen. Your inferior vena cava, your body’s largest vein, carries oxygen-depleted blood back to your heart from the lower part of your body (below your diaphragm).

Detailed explanation-4: -The superior vena cava is located in the thorax (chest), more specifically, it is in the anterior (front) right, superior (above) mediastinum. The superior vena cava starts at the lower border of the first costal cartilage.

Detailed explanation-5: -A vena cava (plural: venae cavae) is a large vein that carries blood to the heart. You have two venae cavae: the superior vena cava and the inferior vena cava. Together, these large veins carry deoxygenated (with the oxygen removed) blood from all over the body to the right atrium of the heart.
