Emphysema is a long-term, progressive disease of the lungs that primarily causes shortness of breath due to over-inflation of the alveoli (air sacs in the lung). In people with emphysema, the lung tissue involved in exchange of gases (oxygen and carbon dioxide) is impaired or destroyed.Emphysema is included in a group of diseases called chronic obstructive pulmonary disease or COPD (pulmonary refers to the lungs).n people with emphysema, the lung tissue involved in exchange of gases (oxygen and carbon dioxide) is impaired or destroyed.

Tonsil stones, which are known scientifically as âtonsillolithsâ, are discrete accumulations of hardened calcium, food debris, mucus and bacteria. Other various anaerobic sulfur compounds are also found in the stones.
Tonsil stones are actually relatively rare, which is one of the reasons why people might always assume that their tonsil stones are actually tonsillitis. Tonsil stones are also called tonsilloliths, and they are typically very small. The larger ones are very rare, and they are always cause for concern. Tonsillitis is more common. Even with people have functioning immune systems, a bacterial infection in the tonsils is frustratingly common for many people.
