Air enters the lungs because the pressure in the atmosphere is greater than the pressure in the lungs.
Lung pressure is lowered by increasing the volume of the lungs. This is achieved by lowering the diaphragm and raising the rib cage.
Air rushes in with chest expansion by moving the muscles of the chest and the diaphragm this creates a lowered pressure with that causes the lungs to inflate.
because of air pressure

Miners stayed in miner's settlements during the gold rush.
only the ribs work with the respiratory system. When there is low pressure in an area air will rush to fill in the space, in high pressure however air will rush away from it. when the ribs move up and out the pressure decreases and the volume increases air will rush in your lungs (inhaling) but when the ribs move down and in it squeezes the lungs increasing the pressure and lowering the volume so air will rush out (exhaling)
No, it is an involuntary rush of air from the lungs immediately upon death.
