Those little bumps all over the back of your throat are actually lymphoid follicles which are part of the immune system. “Lymph glands” are probably what some people would call them.
Their function is to drain the fluid from the throat and nose and tongue region so that your immune cells in these lymphoid follicles can screen for infection to help make the specific antibodies when necessary. You don’t need to worry about them. They may sometimes even appear larger or more inflamed if you come down with a bad cold or the flu.
Your tonsils, which are the lumps at the left and right of the photo, are basically concentrated centres of similar lymphoid tissue but the tonsils play a much more important role in younger children’s immune system, compared to those of adults. If you don’t suffer from sore throats or tonsils infections, then you don’t have to do anything at all to your tonsils, or those lymphoid follicles either, for that matter.
Drink plenty of water, eat a balanced diet, avoid smoking or excessive alcohol, reduce stress, exercise regularly and get 6-8 hours of sleep every night to stay healthy!
