Respiratory system consists of several organs. In the passage of mammalian respiratory system, air enters through the nostrils that enter into the trachea through pharynx and larynx. Trachea ends by dividing into right and left bronchi and permeates into the corresponding lungs. The left bronchus s is longer and narrower than the right. Bronchi are made of rings of cartilage. Thus, trachea indicates the respiratory part of the lower respiratory system, part of the conducting system and the alveolar airway system.
