lymphoid tissue

Lymphoid tissue is specialized tissue in the body that plays a key role in the immune system by producing and housing cells that fight infections. It includes structures like lymph nodes, the spleen, and areas like the tonsils and lymphoid follicles in the gut. These tissues contain immune cells called lymphocytes that detect and respond to germs, viruses, and other harmful substances. Lymphoid tissue acts as a surveillance system, filtering pathogens from the blood and lymph, and helping the body mount a quick and effective immune response to keep us healthy.
