Lymphatics of the stomach and liver

This tutorial explores the lymphatic system, focusing on the lymph nodes surrounding the stomach and liver. It details the role of lymph nodes in filtering lymph and their locations around major arteries. The tutorial covers specific lymph nodes, including gastric, pyloric, gastro-omental, splenic, pancreatic, and hepatic nodes, and explains their drainage paths. It also discusses the celiac lymph nodes and the lymph's return to circulation via the thoracic duct. Clinical notes highlight the impact of lymph node organization on cancer spread. The tutorial concludes with a recap of key points.

What is the primary function of lymph nodes in the abdomen?

• To store nutrients

• To filter lymph and identify pathogens

• To produce red blood cells

• To regulate body temperature

Which lymph nodes drain the superior two-thirds of the stomach?

• Hepatic lymph nodes

• Left gastric lymph nodes

• Right gastro-omental lymph nodes

• Sub pyloric lymph nodes

Where are the splenic lymph nodes typically located?

• Near the proper hepatic artery

• In the hilum of the spleen

• Along the lesser curvature of the stomach

• Near the cardia of the stomach

What is the role of the hepatic lymph nodes?

• To drain lymph from the liver

• To transport nutrients to the stomach

• To filter blood from the spleen

• To produce white blood cells

Which structure receives lymph from all other lymph nodes around the stomach?

• Brachiocephalic vein

• Cisterna chyli

• Portal vein

• Thoracic duct

How does the organization of lymph nodes affect cancer spread in the abdomen?

• It accelerates cancer growth

• It influences the pathways of metastasis

• It has no impact on cancer spread

• It prevents cancer from spreading

Which lymph nodes are associated with the spread of colorectal cancer?

• Sub pyloric lymph nodes

• Hepatic lymph nodes

• Splenic lymph nodes

• Left gastric lymph nodes
