Which statement correctly identifies the venous angle?

• A. It is formed by the internal jugular and subclavian veins
• B. It is formed by the aorta and inferior vena cava
• C. It drains into the right atrium
• D. It is another name for the thoracic duct

Answer: (A)

The venous angle is the junction where the internal jugular vein meets the subclavian vein on each side, forming the angle through which lymphatic fluid returns to the venous system. This is the place where the thoracic duct (on the left) and the right lymphatic duct (on the right) drain into the venous circulation. The other statements don’t fit: the aorta and inferior vena cava don’t form a venous angle, the venous angle isn’t a site that drains directly into the right atrium, and the thoracic duct is a lymphatic vessel that empties into the left venous angle, not the venous angle itself.
