Oral/nasal cavity-
The nasal cavity is the primary intake for air for the respiratory system, consisting of cartilage, muscle and bone. It allows for inhalation of air into the body and warms the air as it enters filtering the air by removing dust, pollen, and other contaminants, purifying the air before it is passed to the inner body. The secondary exterior opening is the oral cavity, it allows for larger quantities of air inhalation, it also has less distance to travel allowing more air to enter the body for faster use, however when inhaled through the oral cavity air is not filtered increasing chances of harmful chemicals.
Pharynx-
Is more commonly referred to as the throat, is tubular, funnel like muscle that extends between the respiratory …show more content…
It ensures that air passes into the trachea and consumable substances into the esophagus.
Larynx-
Located below the pharynx the larynx (voice box), aside from the ability of speech, acts as a form of defensive mechanism, any food passes the epiglottis into the trachea a strong cough reflex forces it back towards the pharynx.
Trachea-
The main respiratory function for the trachea is its provision of a clear, unhindered path for air to enter (inspiration) and exit (expiration) the lungs. Located on the inner walls of the trachea are small hairs, these hairs catch dust and other contaminants from inhaling, generally through the oral cavity due to its lack of filtration, collected contaminates are later disposed of via coughing.
Gas Exchange
Lungs:
• Bronchi-
At the end of the trachea two tubes stem off of its base, each connected to a lung. The bronchi’s connection to the lungs allows air from external respiratory intakes/openings to pass, efficiently, into the lungs. Once in the lungs the bronchi branches into secondary bronchi, much smaller, termed as tertiary
