1. Respiratory System Anatomy

Key Concepts & Definitions

  • Nasal Cavity: A hollow space within the nose that filters, warms, and moistens incoming air; lined with mucous membranes and cilia to trap particles.
  • Pharynx: A muscular tube connecting the nasal cavity to the larynx and esophagus, serving as a passageway for air and food.
  • Larynx: Also known as the voice box; contains vocal cords and functions in phonation, airway protection, and routing air to the trachea.
  • Trachea: A rigid tube (windpipe) that conducts air from the larynx to the bronchi; lined with ciliated mucosa to trap debris.
  • Bronchi and Bronchioles: The main passageways that branch from the trachea into each lung (bronchi) and further subdivide into smaller bronchioles, distributing air throughout the lungs.
  • Alveoli: Tiny air sacs at the end of bronchioles where gas exchange occurs; surrounded by capillaries for oxygen and carbon dioxide transfer.
