What is the diaphragm?
Human BodyAnatomy
Quick Answer
The diaphragm is a dome-shaped muscle beneath the lungs that is the main muscle used for breathing.
The Full Story
When the diaphragm contracts, it flattens and expands the chest cavity, drawing air into the lungs. When it relaxes, the chest cavity shrinks and air is pushed out. Because it is essential for respiration, injury or paralysis of the diaphragm can severely affect breathing. The same word is also used for a thin barrier or partition in devices such as cameras and some engineering systems.
