adenoid
"He explains the adenoid is like a third tonsil. Most of us know, the two tonsils are located at the back of the throat, the adenoid is located at the back of the nose. So when the adenoid is enlarged, because of it's location, it can block or obstruct the airway behind the nose causing breathing problems and subsequently sleeping problems in kids."
"Adenoids are like a sponge - they catch the germs that make you sick, which causes them to increase in size. Most of the time, they return to their normal size when you are healthy again. Sometimes, they remain swollen or enlarged, and become problematic."
"As with tonsillitis, inflamed adenoids are like a red warning light on the dashboard of a car. To take out the light bulb or just to ignore it will do nothing to avoid the upcoming problems."
"Tonsils and adenoids are just like the soldiers of front line of defence of an army, busy in a war, who monitor the harmful viruses and bacterias at very first stage of their attack and on top priority kill them as the try to enter in our body during the process of respiration or swallowing."
