Term
What is the relationship between the resistance to airflow caused by
the diameter of the airway and the phases of respiration in healthy
individuals?
Give this one a go later!
airway resistance remains the relationship between
constant during the phases of airway resistance and
respiration respiration varies
airway resistance
decreases during airway resistance increases during
inspiration due to an inspiration due to a decrease in the
increase in the diameter of diameters of the airways
