The chest wall and the pulmonary apparatus are what make up this system, which is what is used for breathing and giving the body oxygen.

What is the respiratory system?

100

During speech breathing the ______ percentage of the breathing is spent inhaling.

What is 10%?

100

This structure filters, warms, and moistens incoming atmospheric air.

What is the Nasal Passage / Nasal Cavity?

100

This neck muscle acts as an accessory muscle to elevate the sternum during forced inhalation.

What is the Sternocleidomastoid?

100

Lung ______ are composed of two or more volumes.

What are capacities?

200

The diaphragm, abdominal wall, and ribs are what make up this area.

What is the chest wall?

200

During speech breathing ______ percentage of breathing is used exhaling.

What is 90%?

200

This shared passageway connects both the oral and nasal cavities to the esophagus and larynx.

What is the Pharynx?

200

These major and minor chest muscles assist in expanding the thoracic cavity by elevating the upper ribs.

What are the Pectoralis Major and Pectoralis Minor?

200

Maximum amount of air that can be exhaled following a maximum inhalation

What is Vital Capacity? (VC)

300

The components in the rib cage wall muscles that compress the respiratory system when they activate.

What are the expiratory muscles?

300

The most active set of muscles in speech breathing.

What are the abdominal muscles?

300

This structure contains the vocal folds and is topped by a cartilage flap that seals off the airway during swallowing.

What are the Larynx and Epiglottis?

300

This primary dome-shaped muscle flattens upon contraction to expand the thoracic cavity vertically.

What is the Diaphragm?

300

The state of equilibrium in which alveolar pressure and atmospheric pressure are equalized

What is the resting expiratory level? (REL)

400

Direction of exchange of O2 and CO2 in the alveoli

CO2 flows from capillary to alveolar sac, O2 flows from alveolar sac to capillary

400

The two forms of speech breathing.

What are extended steady utterances and running speech activities?

400

This rigid tube carries air down toward the lungs and is kept open by C-shaped rings of hyaline cartilage.

What is the trachea?

400

Located in the anterolateral neck, these three paired accessory muscles elevate the first and second ribs during deep or forced inhalation.

What are the Scalene Muscles?

400

Average total lung capacity of males and females (two answers)

Male: 600 mL

Female: 420 mL

500

This law and this pressure inside the chest cavity allow airflow into the lungs (two answers!)

Boyles Law; negative pressure

500

This (where speech is produced) does not change no matter the position the body is in.

What is the resting lung volume level?

500

The sequential progression of branching airways starting from the widest trunk down to the microscopic site of gas exchange with surrounding capillaries.

What are Bronchi  Bronchioles  Alveoli?

500

Composed of the rectus abdominis, transverse abdominis, and obliques, this muscle group compresses the abdominal viscera to drive exhalation and sustain speech alveolar pressure.

What are the Abdominal Wall Muscles?

500

The equation for functional residual capacity

Expiratory reserve volume (ERV) + Residual volume (RV)
