Lymphocytes are typically sampled from lymphoid tissues such as lymph nodes, tonsils, spleen, and bone marrow. These tissues contain high concentrations of lymphocytes, making them ideal for obtaining a sample for analysis.
Connective tissues dominated by lymphocytes include lymphoid tissues such as lymph nodes, tonsils, and spleen. These tissues are important for immune responses and play a key role in the body's defense against infections.
The main organs of the lymphatic system include the lymph nodes, spleen, thymus, and tonsils. These organs work together to produce, store, and transport lymphocytes (white blood cells) and help in filtering out toxins and waste from the body.

Spleen
The spleen produces lymphocytes. As blood flows through the spleen, lymphocytes attack or mark pathogens in the blood. If pathogens cause an infection, the spleen may also release lymphocytes into the bloodstream.
The tonsils, thymus, and spleen are all components of the lymphatic system, which plays a crucial role in the body’s immune response. These organs help in the production and maturation of lymphocytes, which are essential for fighting infections. The lymphatic system also aids in the transportation of lymph, a fluid that contains infection-fighting white blood cells, throughout the body.
The white pulp of the spleen is involved in producing lymphocytes. This region contains specialized structures called white pulp nodules where lymphocytes are produced and mature.
The spleen, tonsils, and thymus are key components of the lymphatic system and play crucial roles in fighting infections. The spleen filters blood and removes pathogens, while also producing immune cells like lymphocytes that help recognize and respond to invaders. Tonsils trap and filter out pathogens entering through the mouth and nose, providing an early defense against infection. The thymus is responsible for the maturation of T cells, which are essential for adaptive immunity, enabling the body to mount a targeted response to specific pathogens.
Areas of the spleen that contain large numbers of lymphocytes are known as white pulp. White pulp is composed of lymphoid tissue, including T and B lymphocytes, and is responsible for immune responses in the spleen.
The largest lymphatic organ in the body is the spleen, not the tonsils and adenoids. The spleen helps filter blood, store blood cells, and fight infection. Tonsils and adenoids are part of the lymphatic system as well, located in the throat, and play a role in immune function by helping to trap germs that enter through the mouth and nose.
