A
Storing bile produced by the liver
B
Secreting digestive enzymes into the small intestine

Verified step by step guidance1
Step 1: Begin by understanding the role of lymph nodes in the human body. Lymph nodes are small, bean-shaped structures that are part of the lymphatic system, which plays a crucial role in immune defense.
Step 2: Recall that lymph nodes are not involved in digestion or endocrine functions. Specifically, they do not store bile (a function of the gallbladder), secrete digestive enzymes (a function of the pancreas), or produce insulin (also a function of the pancreas).
Step 3: Focus on the primary function of lymph nodes, which is filtering lymph. Lymph is a fluid that circulates through the lymphatic system, carrying white blood cells and other immune components. Lymph nodes act as filters to trap and remove pathogens, debris, and abnormal cells.
Step 4: Understand the immune response facilitated by lymph nodes. When pathogens are detected, lymph nodes activate immune cells such as lymphocytes to fight infections and prevent the spread of harmful agents.
Step 5: Conclude that the correct function of lymph nodes is filtering lymph to remove pathogens and debris, as this aligns with their role in maintaining immune system health.
