Respiratory System Flashcards
Pulmonary ventilation
moving air into and out of the lungs
external respiration
pulmonary gas exchange between blood and alveoli
internal respiration
exchange of gases between blood and cells at capillary beds
tidal volume
the amount of air that moves Into and out of the lungs during normal, quiet breathing. About 500mL
Respiratory capacity
how much air moves into and out of the lungs under different conditions. Affected by size, gender, and physical condition
inspiratory reserve volume
the amount of air that can be inhaled forcibly after a normal inhalation
expiatory reserve volume
the amount of air that can be forcibly exhaled after a normal exhale
residual volume
the amount of air that remains in the lungs even after a forceful exhalation
vital capacity
the amount of air that can be exchanged. TV + IRV + ERV
thyroid cartilage
(adams apple) male DNA = larger
cricoid cartilage
attaches larynx to trachea, internally arytenoid cartilage
trachea
20 c-shaped cartilaginous rings (mucous), wind pipe
Epiglottis
opens and closes when food is swallowed
vestibular folds
false vocal chords, helps to close off food
vocal chords (glottis)
elastic muscle that creates your voice, louder = grater force of air
bronchi
2, first branches
goblet cells
type of mucous membrane
bronchioles
smaller tubes that branch like a tree, 20 levels of branching
alveoli
a grape like object thats surrounded by capillaries, sufactant lining them to prevent collapse
bronchialdialation
bigger bronchioles
bronchioristriction
smaller bronchioles, allergic reaction or hyperventilation
right lung
3 lobes
left lung
2 lobes
serious fluid
lubricates the pleural cavity
