When we inhale the intercostal muscles (between the ribs) and diaphragm
contract to expand the chest cavity. The diaphragm flattens and moves
downwards and the intercostal muscles move the rib cage upwards and out.
This increase in size decreases the internal air pressure and so air
from the outside (at a now higher pressure that inside the thorax)
rushes into the lungs to equalise the pressures.When we exhale the diaphragm and intercostal muscles relax and return to
their resting positions. This reduces the size of the thoracic cavity,
thereby increasing the pressure and forcing air out of the lungs.
Hope its helpfull

ok first of all we inhale a thought our nostrils means nose and that air travels form the windpipe and enters in our chest cavity where where theyfound the lungs and diaphragm now these two are the main characteristics of Breathing when the diagram diseases and the lungs expand the Air enter in the lungs and when the diagram increases and lung srink the air is pushed out by the force and thus the air is released by nostrils again this is the method
