The right lymphatic duct drains lymph from which regions into the right venous angle?

• A Entire right side of the body below the diaphragm
• B Right upper limb, right thorax, right side of head and neck, right lung ✓
• C Both lower limbs and abdominal viscera
• D Right side of the body plus the left lower limb

Explanation

The right lymphatic duct, when present as a single vessel, receives lymph from the right jugular trunk (right head and neck), right subclavian trunk (right upper limb), and right bronchomediastinal trunk (right lung, right heart, right diaphragm). Everything else — both lower limbs, abdomen, left thorax, left upper limb, left head and neck — drains via the thoracic duct into the left venous angle. Thus the right lymphatic duct drains only the right upper quadrant of the body.
