Lec 1 - 5 - Respiratory Pulmonary Function and Structure Flashcards
inhaled gas is 100 percent blank before reaching gas exchange area
humidified
primary barrier between inside body and outside environment; inhaled pathogens and irritants
host defense
air moving across vocal cords
vocalization
lung has no direct blank capacity, it just goes by pressure differences leading to air flow
movement
flow in the lung formula
flow = delta P / R
the role of respiratory system is o2 delivery but the system is controlled by blank
co2
Flow of oxygen formula
Vo2 = inspired ventilation and O2 - expired ventilation and O2
we dont need a high blood pressure to the lungs because lungs have blank
very low blood flow resistance
lung volume is blank percent tissue and blank percent blood
60, 40
nasal/oral passage have shear forces causing synthesis and release of blank
nitric oxide
NO blank the bronchial airways
vasodilates
scm, scalenes, external intercostals, diaphragm are blank muscles
inspiration
internal intercostals, abs, obliques are blank muscles
expiration
expiration is blank unless forced
passive
left lung is blank compared to right due to the blank
smaller, heart
parietal pleura is attached to blank which causes the lungs to actually expand and contract
chest wall
air between lungs
pneumothorax
stuff between visceral and parietal pleura so they dont stick together
surfactant
most blank is in upper airways
resistance
most blank is in lower airways
compliance/gas exchange
conducting airway is aka anatomic blank
dead space
air flow velocity blank as we go deeper into the respiratory tract
decreases
