Respiratory NSG214 Questions & Answers
Verified 100% Correct!
Why do respiratory illnesses become serious quickly?
Due to the body's need for oxygen
What is the function of bradykinin?
Causes airways to constrict which often leads to a cough
What is the function of angiotensin II?
Breaks down and inactivates bradykinin which increases pulmonary hypertension
What is the function of heparin?
Improves lung function, reduces inflammation and protects lung tissue. Reduces the need for
support oxygen.
What is the function of the upper airways?
Moves air in and out of lungs, warms and humidifies air, and traps inhaled particles.
Where are the bronchioles and the alveolis?
The lower airways
What is the function of the alveolis?
Gas exchange with blood and secrete surfactant
What are the components of the parietal pleura?
outer section and chest wall
, What are the components of the visceral pleura?
Inner section, lungs, vessels, and nerves
What muscles make up the accessory muscles of inhalation?
external intercostals, scalene, sternocleidomastoid
What muscles make up the accessory muscles of exhalation?
internal intercostals and abdominal muscles
How is the process of inhalation conducted?
An active process that is initiated by the medulla, the diaphragm contracts which allows the lung
space to become enlarged and pull air in
How is the process of exhalation conducted?
A passive process that is initiated by alveolar CO2 where high CO2 air moves to area of lower
pressure
What portion of the respiratory tract produces sound?
the Larynx
What covers the trachea to prevent aspiration?
Epiglottis
What are the physical characteristics of the right lung?
