Aggregated lymphoid nodules: tonsils

Tonsils form a ring of lymphoid tissue in the lamina propria around oral and nasal pharynges. This palatine tonsil is covered by the stratified squamous epithelium of the oropharynx that invaginates into the tonsil, forming multiple crypts. A partial capsule of dense connective tissue separates the tonsil from underlying connective tissue. 10x
