Unit 13 Respiratory System Review

How will the respiratory system respond to compensate for buffer systems?

• Decrease respiratory rate during metabolic acidosis

• Decrease respiratory rate during metabolic alkalosis

• Increase production of bicarbonate ions

• Increase excretion of bicarbonate ions

What is the correct sequence of airflow in structures of the respiratory zone?

• Alveolar duct to respiratory bronchiole to alveolus

• Trachea to primary bronchus to bronchiole

• Secondary bronchus to tertiary bronchus

• Respiratory bronchiole to alveolar duct to alveolus

Which statement accurately represents physiological buffer systems?

• First line of defense against pH changes

• Utilize bicarbonate to increase pH

• Carbonic acid assists in physiological buffers

• Involve a change in respiratory rate

What is the function of the nasal cavity?

• Block the nasopharynx with swallowing

• Humidify incoming air

• Provide opening to eustachian tubes

• Lighten the weight of the skull

What is the correct sequence of airflow through the conducting zone?

• Bronchi to the bronchioles to respiratory bronchioles

• Respiratory bronchioles to alveolar ducts to alveoli

• Nasal cavity to pharynx to larynx

• Larynx to bronchi to trachea

What is the function of sinuses?

• Cover the glottis with swallowing

• Enhance voice resonance

• Block the nasal cavity during swallowing

• Passage of food and air

The primary bronchi —

• supply the right and left lungs

• travel to each segment of the lungs

• act as part of the respiratory zone

• receive air from the bronchioles

How is most oxygen transported in the body?

• As carbaminohemoglobin

• Bound to hemoglobin

• Dissolved in blood plasma

• In the form of bicarbonate

During the process of inhalation —

• intrapulmonary pressure decreases

• air moves out of the airways

• diaphragm relaxes

• thoracic volume decreases

Which structure supplies air to each lobe of the lung?

• Larynx

• Primary bronchus

• Secondary bronchus

• Trachea
