Step 1
Introduction:
At first, the air enters the human body via nose or the mouth, it then rapidly travels to pharynx, get passed through larynx, which is also referred to as voice box and moves into trachea (wind pipe). Trachea divides into right and left divisions known as right and left bronchus inside the lungs and the bronchus divides further into more smaller branches referred to as bronchioles. The bronchioles which is the smallest, terminates in small air sac like structures referred to as alveoli. These alveoli gets inflated at the time of inhalation and gets deflated at the time of exhalation.
