The air travels through the respiratory system during inhalation in the next order:
Nasal cavity: You inhale air into your nose.
Larynx: The air travels down to this organ, a hollow, tubular structure that plays a key role in phonation, respiration, and deglutition.
Trachea: (Or windpipe) is a wide, hollow and cartilaginous tube that connects the larynx to the bronchi.
Bronchi: The trachea divides into two primary bronchi; they are the main passageway into the lungs.
Bronchioles: The bronchi develop smaller the closer they get to the lung tissue and are then consider bronchioles.
Alveoli: They are tiny air sacs located at the end of the bronchioles, which is the site of oxygen and carbon dioxide exchange in the respiratory system.
