Tonsils are small, glandular structures located at the back of our throat, and they play a crucial role in our immune system. They are part of the body’s first line of defense against infections. Tonsils act as filters, trapping bacteria, viruses, and other pathogens that we might breathe in or swallow. While they are helpful in protecting us from infections, sometimes the tonsils themselves can become infected, leading to conditions like tonsillitis, characterized by a sore throat, fever, and difficulty swallowing. In some cases, recurrent or severe tonsillitis may require their removal through a procedure called a tonsillectomy. Despite their occasional troubles, tonsils serve as important guardians of our health, particularly during our childhood years, when they are most active in defending our bodies against harmful invaders.
