Human respiratory system is divided into two parts that is upper tract and lower tract.Upper tracts is composed of parts such as nose,pharynx and associated structures while lower tract composing of larynx,trachea,bronchi and lungs.
Further we have respiratory and conducting zone whereby conducting zone is the passage way for air movement.Trachea to terminal bronchioles is ciliated for removal of debris.
Respiratory zone begin at bronchioles all the way to the alveoli making it appropriate site for gaseous exchange.Alveoli has different types of cells that performs different functions for example.
(1)Type i alveolar cells
(2)Type ii alveolar cells
(3)Alveolar macrophages
Therefore it is a responsibility of each and every one of us to take care of the respiratory system by avoiding smoking and to practice using face mask for those who have allergies problems so that you may remain safe.
