Light micrograph of a section through a nasopharyngeal tonsil, or adenoid (right) and a minor salivary gland (centre). The tonsils, part of the immune system, are large lymphatic nodules in a mucous membrane. The nasopharyngeal tonsils are located behind the nasal cavity. Each tonsil consists of lymphoid follicles (pink) that contain lymphocyte white blood cells. This minor salivary gland is a mixed gland with both mucus-producing cells (light pink) and serous-producing cells (darker pink). Connective tissue is blue.
