What are the lymph nodes made out of?
lymph nodes are made out of lymphoid tissuethat is able to receive the lymph and return cleaned lymph back into the circulation. Generally the cell types found in the lymph nodes are antigen-presenting cells (specifically dendritic cells), T cells (both helper CD4 T cells and killer CD8 T cells) and B cells (which produce antibodies).
What take place in lymph lodes?
In your blood from your arteries flows into your capillaries. Most of that returns to your heart through your heart. Some returns through the lymph system. The lymph system carries lymph or a fraction of your blood through your system checking for pathogens. It brings them to the lymph nodes. The nodes check the lymph for infection. If the lymph nodes find infection, they start producing antibodies against the infection and inform the rest of the body that infection exist. They sometimes become inflamed when they collect bacteria faster than they can destroy it. Still, they stop it rather than let it go on through the body. They let the lymph go from the lymph nodes back to the veins and back to the heart to recirculate.

(2) They help activate the immune system. Lymph nodes and other lymphoid organs are strategically located sites where lymphocytes encounter antigens and are activated to mount an attack against them.
WHAT IS THE TRIBUTARY REGION OF THE AXILLARY LYMPH NODES?
The tributary region of the axillary lymph nodes primarily includes the upper limb, breast, and the thoracic wall. Lymphatic drainage from these areas flows into the axillary lymph nodes, which play a crucial role in filtering lymph and facilitating immune response. Additionally, they receive lymph from parts of the back and the upper part of the abdomen. This network is essential for monitoring and responding to infections or malignancies in these regions.

Mesenteric lymph nodes play a crucial role in immune responses and help filter and trap pathogens and other harmful substances in the lymphatic system.
