Detailed explanation-1: -Your superior vena cava, your second biggest vein, brings oxygen-poor blood from your upper body to your heart.
Detailed explanation-2: -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-3: -Oxygen-poor blood returns from the body to the heart through the superior vena cava (SVC) and inferior vena cava (IVC), the two main veins that bring blood back to the heart.
Detailed explanation-4: -The SVC is located in the anterior right superior mediastinum. It is the typical site of central venous access via a central venous catheter or a peripherally inserted central catheter. Mentions of “the cava” without further specification usually refer to the SVC.
