Left bronchus
Bronchioles
The inspiratory and expiratory centers are located in the __________.
medulla

What is one of the purposes of the fluid in the pleural cavity?
Lubricate the pleural surfaces to allow them to glide painlessly during lung expansion and contraction
Warm and moisten lung tissue
Prevent bacteria from entering lung tissue
Assist in the diffusion of oxygen across the respiratory membrane
What is the purpose of surfactant?
Facilitate in the diffusion of oxygen across the respiratory membrane
Transport oxygen to the alveoli

Nitrogen
Bicarbonate
When pressure in the lungs drops lower than atmospheric pressure, what occurs?
Air flows out of the lungs.
Air flows into the lungs.
A pneumothorax forms, collapsing the lungs.
The bronchioles constrict, causing respiratory distress.
The primary way oxygen is transported in the blood is:
in the form of bicarbonate ions
in the form of carbamino-hemoglobin
in the form of oxyhemoglobin
dissolved in plasma
What is the primary way carbon dioxide is transported through the body?
Dissolved in plasma
Bound to hemoglobin
Carried in the form of bicarbonate ions
Carried in the form of carbonic acid
Normal aging typically causes which of the following respiratory system changes?
Increased number of alveoli
Increased volume of protective respiratory fluids
Decreased lung rigidity
Decreased mobility of the chest wall
Which factor is key in allowing the body to absorb oxygen and expel carbon dioxide?
Variations in the pressures of the gases
Variations in the volume of the gases
Variations in vital capacity
Variations in tidal volume
What role is served by the pneumotaxic center?
It stimulates the inspiratory center to increase the length and depth of inspiration.
It inhibits the apneustic and inspiratory centers to prevent overinflation of the lungs.
It sends impulses to the abdominal and accessory muscles when more forceful exhalations are needed.
It detects increasing levels of CO2 and triggers inspiration as needed.
