The cavern

The cave is a cavity formed in the body (lung Bud) as a result of fusion of dead tissue (closed cavity). When emptying the contents of the cavity through lead the way (bronchi, the ureters) there is an open cavity. The cavern contain necrotic, festering mass, in which there are microorganisms (pyogenic, putrefactive bacteria, mycobacteria, fungi). Particularly frequent caverns with TB (usually in the lungs, often in the kidneys, liver, spine). Caverns of the lungs can be complicated by bleeding at rupture of blood vessels and pyopneumothorax at the perforation holes in the pleural cavity.
