Which area is not drained by the right lymphatic duct?

• A. Right side of the abdomen
• B. Right side of the thorax
• C. Right side of the head and neck
• D. Right shoulder

Answer: (A)

The right lymphatic duct is responsible for draining lymph from specific regions of the body. It primarily collects lymph from the right side of the head and neck, the right shoulder, and the right side of the thorax. The abdomen is not included in the drainage area of the right lymphatic duct. Instead, lymph from the abdomen and the lower body is generally drained by the thoracic duct, which collects lymph from the left side and the lower half of the body. Thus, the correct response identifies the region that the right lymphatic duct does not serve, namely the right side of the abdomen. This area is not within its anatomical drainage territory, making it a suitable answer to the question.
