The ___ warms, humidifies, and filters air - ANSWER upper airway
The ___ stops food from going into the trachea - ANSWER epiglottis
The ___ is in charge of air conduction which allows cellular transport in the alveoli and
produces surfactant - ANSWER Lower airway and tracheobronchial tree
___ are hair cells that line airway system which sweeps out bacteria and pathogens -
ANSWER Mucociliary clearance
What population doesn't have mucociliary clearance? - ANSWER Smokers
___ reduces the surface tension between the moist membranes and prevents alveoli
from collapsing - ANSWER Surfactant
___ lobes are auscultated on the back of the patient - ANSWER posterior
The ___ lobe is auscultated anteriorly - ANSWER middle
The ___ is a thin layer of tissue that covers the lungs and lines the interior wall of the
chest cavity - ANSWER pleura
The ___ makes pressure change easier in the lungs and allows them to expand and
keeps them 'slippery' - ANSWER Serous membrane
The ___ pleura covers the lungs and the ___ pleura lines the thoracic cavity - ANSWER
Visceral; parietal
___ is the active phase of breathing and the diaphragm flattens and allows air to rush
into the lungs - ANSWER Ventilation
___ is the passive phase of breathing when the diaphragm flattens and air moves out of
the lungs - ANSWER Expiration
True or false: the thorax is a positive pressure space - ANSWER False - its negative
Patients who have a change in surface area available due to water/fluid in the lungs -
ANSWER COPD, chronic asthma pts
Factors influencing diffusion of gases in lungs - ANSWER - change in surface area
available (EX: edema)
- Thickening of alveolar capillary membrane (EX: chronic asthma)
,- Partial pressure (EX: pressure change due to elevation and less oxygen, making
alveolar less expandable)
- Solubility and molecular weight of the gas (EX: smoke inhalation)
___ of the lungs can be altered by elevation. What does it do to the alveoli/ - ANSWER
partial pressure. Makes alveoli less expandable
What type of patients have problems with solubility and molecular weight of the gas in
the lungs? - ANSWER Burn patients and smokers
___ measures how accurately oxygen is carried in the body - ANSWER Hemoglobin
What is oxygen carried in the body? - ANSWER via plasma and RBC
What are the RBC's that oxygen is carried called? - ANSWER oxyhemoglobin
What are the RBC that carry CO2? - ANSWER carboxyhemoglobin
___ is an inadequate amount of oxygen available to the cells - ANSWER hypoxia
___ is difficulty breathing - ANSWER dyspnea
In ___ the heart cells are dead and the damage is irreversible; whereas in ___ the cells
still have an opportunity to oxygenate - ANSWER ischemia; hypoxia
When checking for hypoxia, what are the 2 places on a patient you should look at? -
ANSWER Nail beds and gum lines
In patients with COPD, tissue swelling, asthma, and an excessive amount of secretions
and inflammation they are experiencing ___ - ANSWER dyspnea - difficulty breathing
Patients with ___ use accessory muscle which looks like belly breathing - ANSWER
dyspnea
In ___ there is a decreased rate or depth of air movement into the lungs which may be
caused by giving patients too much narcotics - ANSWER Hypoventilation
True or false: Some people may show no symptoms if they are having a heart attack and
women usually show less signs - ANSWER True
___ is dead of cardiac tissue (myocytes) due to enough decreased oxygenation -
ANSWER Myocardial ischemia
, Factors affecting cardiopulmonary functioning and oxygenation - ANSWER - level of
health
- developmental considerations

True or false: Crackles heard at end of deep respiration in infants is normal - ANSWER
True
In older adults they have a ___ diaphragm compliance which causes a greater risk of
respiratory infection - ANSWER decreased
Curvature of the upper spine in older adults is referred to as ___, refer to physical
changes in respiratory function of older adults - ANSWER Kyphosis
What are physical changes of respiratory functioning in older adults? - ANSWER - barrel
chest

lungs - ANSWER vesicular
___ breath sounds are high-pitched and longer, heard primarily over the trachea -
ANSWER bronchial
