Heya..!
MECHANISM OF BREATHING
It means the inflow(inspiration) and outflow(expiration) of air between atmosphere and the alveoli of the lungs. It is affected by the expansion and the contraction of lungs. There are mainly two processes by which lungs are expanded or contracted.
(1) the downward and upward movement of the diaphragm which increases and decreases the diameter of the thoracic cavity (chest cavity)
(2) the elevation and dipression of the ribs, which lengthens and shortens the thoracic cavity.
