Respiratory System
Anatomy & Function
• The upper respiratory tract filters, warms, and humidifies incoming air.
• Pseudostratified ciliated columnar epithelium lines the conducting airways, aiding in
mucociliary clearance.
• The lower respiratory tract includes the trachea, bronchi, bronchioles, and alveoli.
• Nasal conchae create air turbulence, trapping particles in mucus.
• The pharynx serves as a common passageway for both air and food.
• The oropharynx is lined with stratified squamous epithelium to protect against abrasion.
Key Structures
• Nasal breathing is preferred because it conditions the air more effectively.
• The glottis is the opening to the larynx, involved in voice production.
• The epiglottis covers the larynx during swallowing to prevent aspiration.
• Vocal folds (true vocal cords) are responsible for sound production.
• The trachea connects the larynx to the bronchi and is supported by Cshaped cartilage.
