Respiratory Flashcards
internal ridge at point where trachea divides into L & R primary bronchi
CARINA
end of the conducting zone
TERMINAL BRONCHIOLE
controls the basic rhythm of respiration
MEDULLARY RHYTHMICITY AREA
responsible for 75% of air that enters the lung during quiet breathing
ALVEOLI - provides increased surface area in lungs
DIAPHRAGM
provides increased surface area in lungs
ALVEOLI
a group of disorders in w/c T cells and/or B cells are missing or inactive
SEVERE COMBINED IMMUNODEFICIENCY DISEASE
forced exhalation against a closed rima glottidis as may occur during periods of straining while defecating
VALSALVA MANEUVER
spasmodic contraction of muscles of exhalation; forcefully expels air through nose & mouth
SNEEZING
tissues unable to use O2 properly due to some toxic agent
HISTOTOXIC HYPOXIA
number of secondary bronchi in right primary bronchus
3
number of cartilages that form the wall of the larynx
9
Accessory muscles of inspiration participate only during ___ inhalations
FORCEFUL
Surfactant DECREASES the surface tension of alveolar fluid which ___ the tendency of alveoli to collapse
DECREASES
____ molecular weight = faster rate of diffusion
LOW
Smaller diameter airways lead to ___ airway resistance
INCREASED
