Lymph nodes and their role in immunity

Abstract

Lymph nodes play crucial role in the immune system cell development and response. The spleen, mucosa-associated lymphoid tissue and lymph nodes are the secondary (peripheral) lymphoid organs, but they constitute the immune system. It is known that lymph nodes in the class of secondary (peripheral) lymphoid organs with different functions have different shapes (round, oval or bean-shaped). Lymph nodes connected to each other by lymphatic vessels are located in different regions (thorax, axilla, abdomen, inguinal region and neck region). Lymph nodes are important to generate immune response against foreign molecules in our body. In this proceeding study, we will be reviewing the lymph nodes and their functions in the immunity.
