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
INC/DEC
Contraction of diaphragm & external intercostals → ____ lung volume
INCREASE
INC/DEC
Contraction of the diaphragm → ___ in height/vertical dimension of thoracic cavity
INCREASE
INC/DEC
Accessory muscles of inspiration → ____ in size of thoracic cavity
INCREASE
INC/DEC
Deficiency in surfactant → ___ in lung compliance
DECREASE
INC/DEC
Emphysema → ___ in surface area for gas exchange
DECREASE
INC/DEC
Pulmonary edema → ___ in rate of gas exchange
DECREASE
INC/DEC
Presence of BPG → ___ O2 unloaded from Hb
INCREASE
INC/DEC
Bohr effect: elevated pH levels → ___ Hb affinity to O2
INCREASE
Haldane effect: lower the amount of oxyhemoglobin → ___ CO2 carrying capacity of the blood
INCREASE
