4 Multiple choice questions
- diaphragm relaxes & moves up into original dome shape. This decreases the chest volume & moves air out of the lungs
- -pressure is one determinant of airflow
-resistance is the other determinant of airflow
-the greater the resistance the slower the flow
- The amount of air that remains in the lungs after forcefully exhaling.
- Conducts air in and out of lungs, Humidifies air, Warms air, Filters air.
4 True/False questions
Alveoi → the process by which molecules spread from areas of high concentratiion, to areas of low concentration
Vital capacity → the maximum amount of air that can be exhaled after a maximum inhalation (usually tested with a spirometer)
Ventilation → diaphragm relaxes & moves up into original dome shape. This decreases the chest volume & moves air out of the lungs
Diaphragm → lungs containe over 300 million tiny air sacs providing a huge surface area for gas exchange (Diffusion).
