Boys have high pitched voices when they are young, but their voices deepen as they age. What causes this?
They are able to push more air through the larynx as they get older.
Their lungs grow as they get older.
Their mouths and sinus cavities grow, causing sound to vibrate more deeply.
Their vocal cords grow longer as they get older.
What is the purpose of the cartilaginous rings that surround the trachea?
To prevent food from entering the trachea accidentally.
To prevent the trachea from collapsing between breaths.
To collect foreign particles and prevent them from entering the lungs.
To produce sound as air passes through them.

pons
medulla
midbrain
cerebrum
You go for a morning run. Your respiratory rate will increase because
the pH in your cells is increasing
you are consciously controlling it
your cells are building up more carbon dioxide
you are breathing in more carbon dioxide.

Increased depth and rate of breathing
Decreased depth and rate of breathing
Normal breathing
Irregular breathing pattern
Based on the prefixes and suffixes you've learned, provide a probable definition for the following word: pleuritis.

Explain how the vocal cords can change the pitch of someone’s voice.
By changing the tension and length of the vocal cords
By altering the shape of the mouth
By increasing the volume of air in the lungs
By moving the tongue
Explain the difference between internal and external ventilation.
Internal ventilation refers to the exchange of air within the lungs, while external ventilation involves the exchange of gases between the lungs and the environment.
Internal ventilation involves the exchange of gases between the lungs and the environment, while external ventilation refers to the exchange of air within the lungs.
Internal ventilation and external ventilation are the same processes.
Internal ventilation is a process that occurs only in artificial environments.

Diaphragm and intercostal muscles
Biceps and triceps
Quadriceps and hamstrings
Pectorals and deltoids
