8 'Unnecessary' Organs: New Research Reveals Hidden Roles & Risks
•New research from Harvard Health, New York Post, and NEJM (2023-2026) reveals that 8 organs previously considered 'unnecessary' have hidden immunity or digestive roles.
•The appendix, once thought useless, stores good bacteria and aids intestinal repopulation after diarrhea.
•Gallbladder stores bile for fat digestion; removal due to gallstones is common, with the liver taking over bile production.
•Spleen filters blood and fights infections; its removal increases infection risk, requiring vaccinations.
•Tonsils and adenoids, often removed in children for recurrent infections, can slightly increase respiratory issues but offer benefits like improved sleep.
•The thymus, crucial for T-cell development, when removed, may increase risks of cancer and autoimmune diseases, prompting careful medical decisions.
