Introduction

Under normal circumstances, the tonsils are part of the human immune system and are located on both sides of the throat, specifically at the junction of the back of the mouth and the pharynx. Maintain a balanced and varied diet, with plenty of vitamin-rich fruits and vegetables to enhance local resistance. Avoid excessive use of the voice and speak at a moderate volume to prevent damage to the throat mucosa.

Under normal circumstances, the tonsils are part of the human immune system and are located on both sides of the throat, specifically at the junction of the back of the oral cavity and the pharynx. A detailed explanation is as follows:

The tonsils are situated on both sides of the throat. When the mouth is opened wide, they can be observed in the depressions above the base of the tongue, between the palatopharyngeal arch and the palatoglossal arch. They are扁-oval in shape and constitute an important component of the body's immune system. As gateways to the respiratory and digestive tracts, the tonsils intercept pathogens such as bacteria and viruses entering through the nose and mouth, producing lymphocytes and antibodies to fight infections and protect the body from harmful external substances.

Maintain a balanced and varied diet, consuming plenty of fruits and vegetables rich in vitamins to enhance local resistance. Avoid excessive voice use and speak at a moderate volume to prevent damage to the throat mucosa. Dress appropriately according to weather changes to prevent colds that may lead to tonsillitis. If symptoms such as sore throat or difficulty swallowing occur, seek medical attention promptly for evaluation.
