puzzle respiratory system Flashcards
alveolar and capillary wall together, which form an air-blood barrier that facilitates the simple diffusion of gases
RESPIRATORY MEMBRANE
amount of air that can be forcefully exhaled after a normal tidal exhalation
expiratory reserve volume
movement of air into and out the lungs; consists of inspiration and expiration
VENTILATION
decrease in the size of the bronchiole due to contraction of the muscular wall
bronchoconstriction
small, grape-like sac that perfomrs gas exchange in the lungs
ALVEOLUS
pressure of the air within the alveoli
intra-alveolar pressure
portion of the pharynx flanked by the conchae and oropharynx that serves as an airway
nasopharynx
one sequence of inspiration and expiration
RESPIRATORY CYCLE
substance that acts as a lubricant for the visceral and parietal layers of the pleura during the movement of breathing
pleural fluid
region of the respiratory sytem that includes the organs and structures that provide passageways for air and are not directly involved in gas exchange
conducting zone
pressure of the air within the pleural cavity
intrapleural pressure
mode of breathing that occurs and rest and does not require the cognitive thought of the person
quiet breathing
includes structures of the respiratory system that are directly involved in gas exchange
respiratory zone
tube composed of cartilaginous rings and supporting tissue that connects the lung bronchi and the larynx
trachea
process of adjustment that the respiratory system makes due to chronic exposure to to high altitudes
acclimatization
cartilaginous structures that produces the voice, prevents food and beverages from entering trachea, and regulates the volume of air that enters and leaves the lungs
larynx
amount of air that normally enters the lungs during quiet breathing
tidal volume
amount of air that enters the lungs due to deep inhalation past the tidal volume
inspiratory reserve volume
space between the visceral and parietal pleurae
pleural cavity
small tube that leads from the terminal bronchiole to the respiratory bronchiole and is the point of attachment for alveoli
alveolar duct
leaf-shaped piece of elastic cartilage that is a portio of the larynx that swings to close the trachea during swallowing
epiglottis
increased ventilation rate that leads to abnormally low blood carbon dioxide levels and high (alkaline) blood pH
hyperventilation
graph that describes the relationship of partial pressure to the binding and dissociation of oxygen to and from heme (4 words)
oxygen-hemoglobin dissociation curve
sum of all the partial pressures of a gaseous mixture
total pressure
organ of the respiratory system that performs gas exchange
lung
total number of breaths taken each minute
respiratory rate
innermost layer of the pleura that is superficial to the lungs and extends into the lung fissures
visceral pleura
(also hyperpnea)
mode of breathing that occurs during exercise or by active thought that requires muscle contraction for both inspiration and expiration
FORCED BRETAHING
amount of force that is exerted by gases in the air surrounding any given surface
ATMOSPHERIC PRESSURE
portion of the pharynx bordered by the oropharux superiorly and esophagus and trachea inferiorly; serves as a route for both air and food
laryngopharynx
pressure difference between the intrapleural and intra-alveolar pressures
transpulmonary pressure
condition that results of acute exposure to high altitude due to a low partial pressure of oxygen
acute mountain sickness
(also, inhalation)
process that causes the air to enter the lungs
inspiration
(also, exhalation)
process that causes the air to leave the lungs
expiration
collective name for the multiple branches of the bronchi and bronchioles of the respiratory system
bronchial tree
amount of air that remains in the lungs after maximal exhalation
residual volume
increase in the size of the bronchiole due to contraction of the muscular wall force exerted by each gas in amixture of gases
partial pressure
outermost layer of the pleura that connects to the thoracic wall and diaphragm
parietal pleura
cluster of alveoli
alveolar sac
portion of the pharynx flanked by the nasopharynx, oral cavity, and laryngopharynx that is a passageway for both air and food
oropharynx
branch of bronchi that are 1mm or less in diameter and terminate at alveolar sacs
bronchiole
