The claim that removing the tonsils and appendix has no impact on immune function is not supported by current medical research. Both organs play recognized roles in the body's immune system, and their removal has been associated with measurable, if generally modest, immunological changes.

Tonsils are lymphoid tissue positioned at the entrance of the respiratory and digestive tracts, where they help detect pathogens and initiate early immune responses, including antibody production. Studies have linked tonsillectomy to temporary reductions in certain immunoglobulin levels and altered local immune surveillance in the throat. Similarly, the appendix has been shown to serve as a reservoir for beneficial gut bacteria, helping to repopulate the intestinal microbiome after illness or antibiotic use, and it contains lymphoid tissue involved in mucosal immunity. Research, including large-scale epidemiological studies, has found associations between appendix removal and slightly altered risks for certain gastrointestinal infections and inflammatory conditions later in life.

A common misconception is that because people generally live healthy lives after these surgeries, the organs must be functionally unnecessary. In reality, the body has considerable redundancy in its immune system, meaning other lymphoid tissues and organs can partially compensate for the loss. This compensation explains why most people do not experience obvious or severe immune deficits after these procedures, but it does not mean no impact occurs. The scientific consensus is that these organs contribute to immune function in measurable ways, even though their removal is often medically necessary and generally safe.
