What is the movement of air into and out of
ventilation? the lungs
What is the circulation of blood through the
perfusion? lungs
What are central increased H+ in the brain ECF;
chemoreceptors increased PaCO2;
responsive to? "hypercarbic drive"
,What are decreased pH;
peripheral increased PaCO2;
chemoreceptors decreased PaO2;
responsive to? "hypoxic drive"
What are elastic lungs recoil due to elastin, collagen,
forces? fibrin
What are surface surface tension due to water-air
forces? interface
opposition to flow caused by the
What is airway
forces of friction; primarily
resistance?
determined by airway radius
What is the ease with which the lungs can be
distensibility of inflated
the lungs?
What is lung neonates and children;
distensibility emphysema
increased in?
What is lung elderly;
distensibility pneumonia, pulmonary edema, ARDS,
decreased in? atelectasis, fibrosis
, complex substance lining the alveoli
and smallest bronchioles containing
phospholipids and a number of
apoproteins which reduces surface
What is
tension throughout the lungs, thereby
surfactant?
contributing to its general
compliance;
stabilizes the alveoli and keeps them
dry
What produces produced by the Type II alveolar cells
surfactant?
What is Ohm's velocity = driving force/resistance
law?
What is Poiseuille resistance = (8 x viscosity x length) /
law? (pi x radius^4)
What happens if the resistance goes up
the radius in the
lungs goes
down?
How is the the top of the lungs are more
ventilation distended and less compliant whereas
distributed in the the lower lung is small and highly
lungs? compliant
