streaks of air that outline muscles of the thorax and sometimes the neck. - ANSSubcutaneous
Emphysema
At what costal interspace does the diaphragm lie when the lungs are fully inflated - ANSTenth
,Air collecting behind the sternum and dissecting up into the soft tissue of the neck is called -
ANSMediastinal Emphysema (pneumomediastinum)
An accumulation of fluid in the pleural space, sometimes caused by heart failure or pulmonary
embolus, is called - ANSEffusion
What are the two major functions of the respiratory system ? - ANSoxygenation of blood and
removal of waste (CO2)
What does the lower respiratory system consist of? - ANStrachea, bronchi and bronchioles
The lower respiratory system is responsible for _________________ from the upper respiratory
system. - ANSconducting air
The tracheobronchial tree is lined with a _______________________. - ANSmucous membrane
What are the hair-like projections found with in the tracheobronchial tree? - ANScilia
What purpose does cilia serve? - ANSIt prevents dust and foreign particles from reaching the
lungs.
What can happen if cilia become damaged? - ANSWhen particles are allowed to enter the
respiratory system (because of damage) the foreign particles produce a disease process.
Where does external respiration take place? - ANSin the lung parenchyma (alveoli)
Explain the process of internal respiration: - ANSO2 attaches to hemoglobin molecules in red
blood cells and circulates to various tissues in the body.
During respiration which muscles are stimulated to contract? - ANSThe diaphragm and
intercostal muscles
What happens to the lungs when the muscles responsible for respiration contract? - ANSThey
expand and fill with air
Pulmonary circulation provides the ____________ with oxygenated blood. - ANSbody
What is the inner lining surrounding and attached to the lung wall called? - ANSvisceral pleura
Irregular thickening of linear chest markings due to excessively viscous mucus is the
radiographic appearance in what pathology? - ANSCystic fibrosis
Surfactant consists of lipoproteins and serves what purpose in the respiratory system? - ANSIt
provides the proper surface tension in the alveoli, allowing full external respiration.
, What types of images best demonstrate a rounded thickening of the epiglottic shadow and what
disease is characteristic of this? - ANSSoft tissue AP and lateral neck images; Epiglottitis
How are the various types of pneumonia characterized? - ANSby their cause and location in the
lung
How does a lung abscess appear? - ANSAs a spherical density with a hazy, poorly defined
periphery. May have air/fluid level

extended time is? - ANSMycobacterium tuberculosis
Pulmonary infiltration(s), most commonly in the periphery of the parenchyma, that may resemble
pneumonia are the radiographic appearance of what? - ANSAcute coccidioidomycosis
Explain why respiratory syncytial virus is responsible for an increased rate of nosocomial
infections - ANSDue to the ability of the virus to persist on surfaces for many hours
