It carries oxygen-poor blood from the head, neck, arms, and upper chest into the right atrium. Clinicians reference it often in imaging, central venous access, cardiac devices, and evaluation of chest symptoms. It also matters in conditions that block venous flow, such as Superior Vena Cava obstruction (often discussed as \u201cSVC syndrome\u201d)."}
