From the nose, the air passes through the pharynx (the cavity behind the nose and mouth) and the larynx (the voice box). The air then enters the trachea. The trachea carries the air toward the lungs. Before reaching the lungs, the trachea splits into two tubes called the primary bronchi. Each tube enters one lung. Within the lungs, the primary bronchi divide into smaller and smaller tubes, finally branching into extremely tiny tubes called bronchioles.
Share to: In the breathing system, the air enters at the nostrils (nares) , passes through the nasal cavity (where some smell detectors are located) , and enters the trachea.Sid â¦ e branches of this system the Eustachian tubes communicate with the middle ear to allow for the balancing or air pressure across the eardrum.he air we breath in normally enters through our nose. This is  because The hairs inside our nostrils catch pathogens(germs) and  particles. Also when the air enters our nas â¦ al cavity small hairs  called cillia further help to catch pathogens, as well as  moistening and warming the air.
