-Sound production.
-O2, CO2, and H+ (pH) regulation. - ANS Functions of the Respiratory System.
-Upper respiratory system (nose, pharynx, associated structures).
-Lower respiratory system (larynx, trachea, bronchi, lungs). - ANS Structural Classification of
respiratory system.
-Conducting zone (nose, pharynx, larynx, trachea, bronchi, bronchioles, and terminal
bronchioles).
-Respiratory zone (respiratory bronchioles, alveolar ducts, alveolar sacs, and alveoli). -
ANS Functional Classification of respiratory system.
Filters, warms, and moistens air before sending it to the lungs. - ANS Conducting zone.
Site of gas exchange. - ANS Respiratory zone.
-Mostly ciliated epithelium.

,-Becomes progressively thinner from the nasal cavity to the alveoli.
-Goblet cells produce mucus.
-Contain antimicrobial proteins and IgA. - ANS Mucous Membrane (AKA Mucosa).
-Mucous secretions contain this.
-Increases the viscosity of mucus to better trap particles and microbes. - ANS Mucin.
-Conditions air (warms, moistens, and filters).
-Detect olfactory stimuli.
-Modify speech vibrations. - ANS Nose functions.
-Nasal vestibule.
-Olfactory region.
-Respiratory region. - ANS Nose regions.
-Immediately internal to nostrils.
-Vibrissae trap large particles. - ANS Nasal vestibule.
-Lined with mucosa. Cilia sweep mucus toward the throat and cilia become sluggish in cold
temperatures.
-Extensive vasculature. - ANS Respiratory region.
Surgery to alter the shape of the nose. - ANS Rhinoplasty.
-Used to repair a fractured nose or deviated nasal septum, but also used for cosmetic reasons.
-Nasal cartilage is reshaped, nasal bones are fractured and repositioned.
-Internal packing and a splint are inserted to help it heal in the new shape. - ANS Clinical
Connection: Nose Jobs.

, -Lined by pseudostratified ciliated columnar epithelium (continuous with mucosa of nasal
cavity).
-Mucus is swept from each sinus--> nasal cavity--> pharynx--> swallowed. - ANS Paranasal
Sinuses.
-Inflammation of nasal mucosa.
-Excessive mucus production.
-Nasal congestion.
-Postnasal drip. - ANS Clinical Connection: Rhinitis.
-Posterior to nasal cavity and extends to larynx.
-Contraction of skeletal muscles assists in deglutition.
-Function: Passageway for air and food. - ANS Pharynx.
-Nasopharynx.
-Oropharynx.
-Laryngopharynx. - ANS Regions of the Pharynx.
-Normally, only air passes through.
-Auditory tubes equalize air pressure.
-Pharyngeal tonsil. - ANS Nasopharynx.
Lingual and palatine tonsils. - ANS Oropharynx.
Common passageway for food and air. - ANS Laryngopharynx.
-Passageway for air.
-Prevents food from entering respiratory tract.
-Sound protection.
