inspiration and expiration occur due to changes of volume and pressure inside thorax

ribs go downwards and inwards while diaphragm relaxes. Bulges go upwards since the organs below are contracting.

internal intercostal muscles contract and external intercostal muscles relax.

# data[].attributes.body
Since the pressure is low inside the lung, air will go inside through trachea to do the gas exchange.

# data[].attributes.body
both these two actions lead to the lower pressure inside the thorax than outside. Thus, the volume of the chest increases.

# data[].attributes.body
the diaphragm contracts and pull down which give more volume to lungs.

# data[].attributes.body
it requires pressure changes to occur in the lungs, so that air can be forced in and out of the alveoli. Ventilation process has 2 parts: inspiration and expiration.

External intercostal muscles contract pulling the ribs up and out.
