Of many other lymphatic system disorders, tonsillitis is another disease caused by an infection of the tonsils, the lymphoid tissues present in the back of the mouth at the top of the throat. These lymphoid tissues help filter out bacteria and when infected, they become swollen and inflamed, leading to a sore throat, fever, and difficulty and pain while swallowing. Explain why a tonsillectomy in a child is less likely to involve complications than the same procedure for an adult.
