Chest
Most penetrating injuries are chest wounds and have a mortality rate (death rate) of under 10%. Penetrating chest trauma can injure vital organs such as the heart and lungs and can interfere with breathing and circulation. Lung injuries that can be caused by penetrating trauma include pulmonary laceration (a cut or tear) pulmonary contusion (a bruise), hemothorax (an accumulation of blood in the chest cavity outside of the lung), pneumothorax (an accumulation of air in the chest cavity) and hemopneumothorax (accumulation of both blood and air). Sucking chest wounds and tension pneumothorax may result.
Penetrating trauma can also cause injuries to the heart and circulatory system. When the heart is punctured, it may bleed profusely into the chest cavity if the membrane around it {the pericardium) is significantly torn, or it may cause pericardial tamponade if the pericardium is not disrupted. In pericardial tamponade, blood escapes from the heart but is trapped within the pericardium, so pressure builds up between the pericardium and the heart, compressing the latter and interfering with its pumping. Fractures of the ribs commonly produce penetrating chest trauma when sharp bone ends pierce tissues.

Famous quotes containing the word chest:
“It was obvious that the size of your chest was in direct proportion to the size of your salary.”
—Cynthia Hess, U.S. exotic dancer. As quoted in Newsweek magazine, p. 19 (April 25, 1994)
“This socialism will develop in all its phases until it reaches its own extremes and absurdities. Then once again a cry of denial will break from the titanic chest of the revolutionary minority and again a mortal struggle will begin, in which socialism will play the role of contemporary conservatism and will be overwhelmed in the subsequent revolution, as yet unknown to us.”
—Alexander Herzen (1812–1870)
“Man is head, chest and stomach. Each of these animals operates, more often than not, individually. I eat, I feel, I even, although rarely, think.... This jungle crawls and teems, is hungry, roars, gets angry, devours itself, and its cacophonic concert does not even stop when you are asleep.”
—René Daumal (1908–1944)
