A

To provide a pathway for air between the larynx and the bronchus

17

What provides a pathway for air between the larynx and the bronchus

A

Trachea

18
Q

What is the function of the nose/nasal cavity?

A

To warm, moisten and filter air entering the respiratory system

19
Q

What warms, moisten and filter air entering the respiratory system

A

Nose/nasal cavity

20
Q

What are the three functions of he pharynx?

A

To provide passageway for food and air

To warm, moistens and protects from infection (mucous membrane)

To assists with speech
Involved with hearing (nasopharynx)

21
Q

What provides passageway for food and air in the respiratory system?

A

Pharynx

22
Q

What is the function of the larynx?

A

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
