How respiratory system works?
What are the components of respiratory system?
Explanation:
Our lungs expand when we breathe in through our nose and mouth. That air moves down our trachea, through your bronchi and into the bronchioles, where it enters your alveoli where blood capillaries are passes which load oxygen and unload carbondioxide gas which can be removed from our body through exhalation. Nose, mouth, throat (pharynx), voice box (larynx)
, windpipe (trachea)
, large airways (bronchi) and lungs are the main components of our respiratory system.
