  • Removes debris/airborne particles
• Pharynx
  • Receives air from the nasal cavity and air, food, and water from the oral cavity
• Larynx
  • Also known as the voice box
  • Protects lower respiratory tract from getting food into the trachea while breathing
• Trachea
  • Empty tube which is separated into two branches that serve as passageway of air into the lungs
• Bronchi (Bronchus)
  • Branching tubes
• Bronchioles
  • Hair-like tubes entering each lung
• Alveoli
  • Air sacs
  • Bubble-like branch structures connected to the bronchioles
  • Exchanging of gases
• Lungs
