Where is the largest lymph node in the body?

Is the liver a lymphoid organ?

Liver as a Lymphoid Organ

Besides these well-known functions, it is also considered as a lymphoid organ (2).

What are the lymphatic organs and explain the function of each?

The primary lymphoid organs are the red bone marrow, in which blood and immune cells are produced, and the thymus, where T-lymphocytes mature. The lymph nodes and spleen are the major secondary lymphoid organs; they filter out pathogens and maintain the population of mature lymphocytes.

What lymphatic organ can you live without?

The kidney contains a network of lymphatic vessels that clear fluid, small molecules, and cells from the renal interstitium. Through modulating immune responses and via crosstalk with surrounding renal cells, lymphatic vessels have been implicated in the progression and maintenance of kidney disease.

Which is the second largest lymphatic organ?

The main secondary lymphoid organs are lymph nodes, spleen and tonsils. So, our first option is the liver, which is the largest gland of the human body, not the largest lymphoid organ. Second option is a kidney. The only role of the kidney in lymphatic systems is elimination of toxic products from lymph.
