Primary lymphoid organs allow lymphoid stem cells to proliferate, differentiate, and mature while secondary lymphoid organs encourage functional lymphoid cells to grow. In addition, primary lymphoid organs contain only T cells or B cells, while secondary lymphoid organs contain T cells and B cells , respectively.

What are the functions of primary and secondary lymphoid organs?
Primary lymphoid tissues (thymus, fetal liver and bone marrow) nurture lymphocyte development, whereas secondary lymphoid organs support lymphocyte maturation, survival and activation. Secondary lymphoid organs are distributed strategically throughout the body and drain antigenic material from tissues and organs.
What is a secondary lymphoid organ?
Secondary lymphoid organs (SLOs) include lymph nodes (LNs), spleen, Peyer's patches (PPs) and mucosal tissues- the nasal associated lymphoid tissue (NALT), adenoids, and tonsils.
What is the function of the secondary lymphoid organs?
Secondary lymphoid organs (spleen, lymph nodes, mucosal associated lymphoid tissue) provide the environment for the proliferation and maturation of cells involved in the adaptive immune response, for filtering and trapping antigens.
What is the function of the primary lymphoid organs?
What are Primary lymphatic organs? Primary lymphatic organs are where lymphocytes are formed and mature. They provide an environment for stem cells to divide and mature into B- and T- cells: There are two primary lymphatic organs: the red bone marrow and the thymus gland.
What are primary and secondary lymphoid organs give examples?
Primary lymphoid organs: These organs include the bone marrow and the thymus. They create special immune system cells called lymphocytes. Secondary lymphoid organs: These organs include the lymph nodes, the spleen, the tonsils and certain tissue in various mucous membrane layers in the body (for instance in the bowel).
Is malt a secondary lymphoid organ?
Secondary lymphoid organs (including the spleen, lymph nodes, and MALT)
...
Key terms.
| Term | Meaning |
|---|---|
| Spleen | Secondary lymphoid organ that filters blood and stores erythrocytes and lymphocytes |
| Lymph nodes | Secondary lymphoid organ that filters lymph |
| MALT | Mucosa-associated lymphoid tissue, a type of secondary lymphoid organ |
Is the thymus a secondary lymphoid organ?
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.
Which is not a secondary lymphoid organ?
So, the correct answer is 'Thymus gland'.
What is the first lymphoid organ to appear in the embryo?
According to our model, T cells were the first lymphocytes to acquire variable-diversity-joining-type receptors, and the thymus was the first lymphoid organ to evolve in vertebrates to deal with potentially autoreactive, somatically diversified T cell receptors.
