Verified step by step guidance

Understand the primary functions of lymph nodes: Lymph nodes are small, bean-shaped structures that are part of the lymphatic system. They play a crucial role in filtering lymph, a fluid that circulates through the lymphatic system, to remove pathogens and debris.

Recognize the role of lymph nodes in the immune system: Lymph nodes facilitate the maturation of immune cells, such as lymphocytes, which are essential for mounting an immune response against infections.

Identify the housing function of lymph nodes: Lymph nodes house lymphocytes, including T cells and B cells, which are critical for fighting infections and maintaining immune surveillance.

Consider the process of hematopoiesis: Hematopoiesis is the process of producing blood cells, including red blood cells, which primarily occurs in the bone marrow, not in lymph nodes.

Determine the incorrect function: Based on the understanding of lymph node functions and the process of hematopoiesis, identify that 'Produce red blood cells' is not a function of lymph nodes.
