Trachea
What is the function of the alveoli
To exchange oxygen and carbon dioxide molecules to and from the bloodstream
(gaseous exchange/pulmonary diffusion)
What component of the respiratory system has the function of gaseous exchange
alveoli
What is the function of the bronchioles?
To provide a pathway for air between bronchus and alveoli
What provides a pathway for air between bronchus and alveoli
Bronchioles
What provides a pathway for air between trachea and bronchioles
Bronchi/bronchus
What is the function of the Bronchi
To provide a pathway for air between trachea and bronchioles
What is the function of the trachea
To provide a pathway for air between the larynx and the bronchus
What provides a pathway for air between the larynx and the bronchus
Trachea
What is the function of the nose/nasal cavity?
To warm, moisten and filter air entering the respiratory system
What warms, moisten and filter air entering the respiratory system
Nose/nasal cavity
What are the three functions of he pharynx?
To provide passageway for food and air
To warm, moistens and protects from infection (mucous membrane)
To assists with speech
Involved with hearing (nasopharynx)
What provides passageway for food and air in the respiratory system?
Pharynx
What is the function of the larynx?
To allow air to pass through to the trachea whilst stopping food and liquids from entering the respiratory tract
To house the vocal cords which manipulate pitch and volume essential for sound and speech
What are the components of the upper respiratory system?
Nasal cavity
Oral cavity
Pharynx
Larynx
What are the components of the lower respiratory system?
Trachea
Bronchi
Bronchioles
Alveoli
Lungs
