Tonsils
Amígdalas
Also: Tonsilas (regional variant)
Where are the tonsils?
MedlinePlus describes the tonsils as lumps of tissue at the back of the throat, two of them, one on each side. The National Cancer Institute (NCI) dictionary defines a tonsil as one of two small masses of lymphoid tissue on either side of the throat. When checking for tonsillitis, MedlinePlus says, a health care provider looks at the throat and neck, checking for things such as redness or white spots on the tonsils and swollen lymph nodes.
What do the tonsils do?
According to MedlinePlus, the tonsils, along with the adenoids, are part of the lymphatic system, which clears away infection and keeps body fluids in balance. Tonsils and adenoids work by trapping the germs coming in through the mouth and nose. The MedlinePlus en español article on tonsillectomy states that the tonsils help protect against infections.
Terms built on the tonsils
Tonsillitis is an inflammation (swelling) of the tonsils. MedlinePlus says the cause is usually a viral infection and that bacterial infections such as strep throat can also cause it. For a child with tonsillitis, MedlinePlus says to get emergency care right away if the child has trouble breathing, starts drooling, or has a lot of trouble swallowing. Emergency signs need urgent care (call 911 in the U.S.).
A tonsillectomy is surgery to remove the tonsils. The MedlinePlus en español tonsillectomy article notes that the tonsils are often removed together with the adenoids, and it calls the removal of the adenoids an adenoidectomy.

The U.S. Department of Health and Human Services Office for Civil Rights states that two federal laws, Title VI of the Civil Rights Act of 1964 and Section 1557 of the Affordable Care Act, require programs that receive its funding to provide language access services free of charge.
