Visceral lymph nodes are located in which area?

Visceral lymph nodes are located in which area?

• A. Omentum
• B. Peritoneum
• C. Retroperitoneum
• D. Mesentery

Answer: (B)

Visceral lymph nodes reside within the peritoneal cavity, along the surfaces covering the abdominal viscera. The peritoneum lines the abdominal cavity and the visceral peritoneum envelops the organs, so the lymph nodes that drain these organs are located in this space. They are not in the retroperitoneum, which lies behind the peritoneum, nor are they confined to a single peritoneal structure like the omentum or the mesentery, though those peritoneal structures do contain vessels and lymphatics connected to those nodes. Therefore, the area housing visceral lymph nodes is the peritoneum.
