LUNG VOLUMES (SPIROMETRY) LAB REVIEW QUESTIONS Flashcards
What is pulmonary ventilation?
pulmonary ventilation is the movement of air between the atmosphere and lungs (breathing)
What is the average tidal volume in liters for the average adult?
the average tidal volume is 500mL and .5L
Which lung volume represent the largest volume?
the largest lung volume is inspiratory lung capacity (3L)
Define tidal volume.
tidal volume is the average amount of air breathed in at rest
What instrument is used to measure breathing volume?
a spirometer is used to measure breathing volume
If you inhale maximally, what is the name of the air that you completely exhale?
it is called slow vital capacity (SVC/ VC)
How does the decrease in vital capacity influence an athletes ability?/
a decrease in vital capacity causes a decrease in athletic ability; especially in endurance sports
Calculate the IRV of an individual with a vital capacity of 4400mL, an ERV of 1300mL, and a TV of 500mL.
2600mL
How does closing of respiratory passages change the rate of airflow?
the rate of airflow slows
Asthma occurs due to an obstruction of the bronchioles in the lungs.
What does this indicate?
asthma indicates a resistance of airflow into the lungs
