The pharynx is protected by the simplest lymphoid organ known as the tonsils. The tonsils are classified as secondary lymphoid organs, and contain follicles and have germinal centers.
thymus. It is a primary lymphoid organ responsible for the maturation of T lymphocytes and is located in the chest behind the sternum. The thymus plays a key role in the development of the immune system, particularly in early life.
Tonsil
The portion of the pharynx that connects to the nose and contains the adenoids is the nasopharynx. Adenoids are a collection of lymphoid tissue located in the back of the nasopharynx, near the opening of the eustachian tube. They are part of the immune system and help protect the body from infections.
The thymus is a lymphoid organ that does not contain reticular connective tissue. Instead, it is composed of epithelial cells and lymphocytes. This organ plays a crucial role in T cell maturation and development.
The pharynx is a apart of the Respiratory system
The tonsils are part of the mucosa-associated lymphoid tissues (MALT) and help remove pathogens that enter the pharynx (throat). They play a role in the immune response to protect the body from infection in the respiratory and digestive tracts.

Tonsil
Lingual tonsils are located at the base of the tongue, near the junction of the oral cavity and pharynx. They are a collection of lymphoid tissue that helps protect against infections.

The White Blood Cells form in the lymphoid organ because the lymph system is not a closed system and contains a fluid called the lymph.
