• Nasal cartilage

What is the role of the false vocal cords?

• They do not produce sounds but help close the airway during swallowing

• They produce high-pitched sounds

• They filter bacteria from inhaled air

• They assist in the digestion of food

What can cause hoarseness or loss of voice according to the text?

• Damage to the thyroid cartilage

• Inflammation of the larynx

• Relaxation of the vocal cords

• Contraction of the epiglottis

How do the vocal cords produce sounds?

• By vibrating as air passes through them

• By remaining still and allowing air to pass

• By expanding and contracting

• By absorbing sound waves

What is the function of the glottis? The epiglottis?

• Glottis: Produces sound; Epiglottis: Prevents food from entering the trachea

• Glottis: Filters air; Epiglottis: Produces sound

• Glottis: Absorbs nutrients; Epiglottis: Filters air

• Glottis: Supports the trachea; Epiglottis: Supports the larynx
