What role does tonsil play in human body?

Tonsils are an important part of human immune system. Its position and special tissue structure make it play a role in helping the whole immune system grow and stimulating children to produce antibodies. The specific functions are: (1) protecting respiratory tract and digestive tract from bacterial invasion; Produce immune bodies resistant to bacterial infection; Lymphocytes are produced and transported into the blood. Why is tonsil inflamed? Tonsils are the "natural barrier" of human body and the "first line of defense" against respiratory diseases. Once this line of defense is broken, it will in turn bring a lot of harm to the human body. For example, when a child has a cold or fever, the tonsils are often inflamed. If it is often inflamed repeatedly, it will hinder the toxin from being discharged from the tonsils and easily become a "lesion". This tonsil "focus" can also cause many systemic diseases, such as rheumatic fever, glomerulonephritis, rheumatic heart disease, rheumatoid arthritis and other diseases. What's the difference between tonsils and proliferators? Tonsils are small and round things that protrude slightly from both sides of the throat to stop and kill bacteria and prevent them from invading the lungs through the trachea. You can see your child when he sticks out his tongue and says "ah" or yawns. Another gland closely related to the tonsil is the proliferative gland, which is similar to the tonsil in structure and function. From the deep throat to the nasal cavity, the developed glands of lymph glands are called proliferators, which can only be seen through some special instruments. How does tonsil get sick? Tonsils are a bit like sponges. They have many holes and cracks. When attacked by bacteria and other microorganisms, it will become inflamed and swollen. In this way, it will lead to tonsillitis or other painful diseases, such as otitis media and sinusitis. Tonsils and their similar proliferators are the immune organs of human body. Whenever we get sick, they will swell up and play an immune role. It takes about 3 to 9 months, which is a process of increasing and decreasing. In some extreme cases, the diffuser is enlarged and enters the nasal cavity, so that children can only breathe through the mouth. Hyperplasia can also make children have a heavy nasal sound when speaking, and it is also easy to cause middle ear infection, or press the auditory nerve outward, leading to hearing loss or deafness. Similarly, tonsil hypertrophy will bring some troubles, such as dysphagia. When tonsils and proliferators are enlarged, they will cause snoring during sleep, and it is easy to wake up during sleep. What is the difference between tonsillitis and general sore throat? Tonsillitis is a more serious disease with sore throat, which is caused by many different viruses and bacteria. Once the tonsils are inflamed, the throat will be red and swollen, and there will be pain when swallowing saliva, so your child may not even dare to eat. If the child's throat is facing the light, it will be obvious that his tonsils are covered with white, gray or yellowish things. Other symptoms of tonsillitis include: high fever, earache, hoarseness, dyspnea, physical fatigue, vomiting, and lymphadenopathy on both sides of the throat. In contrast, the average sore throat is because of that.
