The Nose Knows..show for 2-11-26

The nose’s main functions are breathing, smelling, and conditioning the air; it warms, humidifies, and filters inhaled air before it reaches the lungs, protects the respiratory system from pathogens, enables our sense of smell (which significantly impacts taste), and adds resonance to our voice, making it a vital part of the respiratory and sensory systems.

Nasal Conchae .

Bones, cartilages and mucosa with a focus on the lateral wall of the nasal cavity. The nasal conchae (also known as turbinates) are bony plates located on the lateral wall of the nasal cavity. There are three nasal conchae in each nasal cavity including the superior, middle and inferior nasal conchae.

Function . What is the function of the nose? AI Overview Nose and throat  The nose’s main functions are breathing, smelling, and conditioning the air; it warms, humidifies, and filters inhaled air before it reaches the lungs, protects the respiratory system from pathogens, enables our sense of smell (which significantly impacts taste), and adds resonance to our voice, making it a vital part of the respiratory and sensory systems.   

Air Treatment & Protection Filtering: Mucus and tiny hairs (cilia) trap dust, germs, and allergens, preventing them from entering the lungs.  Humidifying: The mucous membrane adds moisture to dry air, protecting the throat and airways.  Warming/Cooling: It adjusts the air’s temperature to body temperature, making it more comfortable for the lungs.  Defense: It produces immune substances (immunoglobulins) to fight inhaled bacteria and viruses.  Smell & Taste Olfaction: Specialized nerve cells in the upper nasal cavity detect odor molecules, giving us our sense of smell.  Flavor Perception: Smell is crucial for flavor; when you have a cold and can’t smell, food seems tasteless.  Other Functions Voice Resonance: The nasal passages and sinuses add tone and depth to your voice.  Breathing Pathway: It’s the primary entrance for air, ensuring proper oxygenation, especially during sleep when nasal breathing is superior to mouth breathing

Treatment:

Nasal Cavity . What is the nasal cavity? AI Overview Nose and throat | healthdirect The nasal cavity is the air-filled space inside your nose, divided into two passages by the nasal septum, that serves as the entrance to the respiratory system, filtering, warming, and humidifying inhaled air while housing the sense of smell. Lined with mucus and tiny hairs, it traps dust, warms and moistens air, and contains olfactory receptors for smell, directing air to the lungs and connecting to the throat (nasopharynx).

Structure & Location Location: Above the mouth’s roof, behind the nose, and connected to the nasopharynx at the back.  Division: A central wall (nasal septum) separates it into left and right passages (fossae).  Key Features: Includes scroll-like bones called turbinates (conchae) that increase surface area, and is surrounded by air-filled paranasal sinuses.

Functions Respiration: Filters large particles with hairs, warms air with blood vessels, and humidifies it with mucus.  Olfaction (Smell): Contains specialized nerve endings for detecting odors.  Immune Defense: Mucus traps pathogens, and the lining protects deeper respiratory structures.  Drainage: Allows drainage of mucus and secretions from sinuses.  Key Regions Nasal Vestibule: Just inside the nostril, lined with skin and coarse hairs.  Respiratory Region: The main area for conditioning air (warming, humidifying, filtering).  Olfactory Region: Located in the upper part, containing smell receptors (olfactory epithelium).
