Solution

The lymphatic system is an extensive network that helps to balance body fluid levels and acts as immunological filters that helps to defend the body against infections. It is made up of a network of lymphatic vessels that carry lymph. compound structures in the lymphatic circulation system that filter the lymph are lymph nodes. Lymph nodes are located throughout the body but the largest groupings are found in the neck, armpits, and groin areas.

Axillary lymph nodes: Bean-Shaped encapsulated structures present in the arm pit and helps in draining lymph from breasts, upper arm & under arm regions.

Gut-Associated lymph nodes (GALT): These are the lymphatic tissue contains the components of MALT (mucosa-associated lymphatic tissues) that protects the body from invasion in the Gut (Gastrointestinal tract) region.

Spleen: Present in the upper part of abdomen, which is a large lymphoid organ and have blood cleansing functions and site of hematopoiesis in fetus.

Function: Filters blood & entraps antigen foreign materials & provides defense against blood borne antigens

In General:

The axillary, GALT lymph nodes & Spleen acts as a secondary lymphoid organs, which consists of immune cells including (T-cells, B-cells, lymphocytes, NK cells, Dendritic cells, macrophages, etc) and helps in body immune response mechanism and fight against infections.
