5 Written questions
4 Multiple choice questions
- -pressure is one determinant of airflow
-resistance is the other determinant of airflow
-the greater the resistance the slower the flow
- the maximum amount of air that can be exhaled after a maximum inhalation (usually tested with a spirometer)
- an active process in which the intercostal (rib) muscles and the diaphragm contract, expanding the size of the chest cavity and causing air to flow into the lungs
- The amount of air that remains in the lungs after forcefully exhaling.
4 True/False questions
Cellular Respiration → exchange of O2 and CO2 between the alveoli and circulating blood in the pulmonary capillaries.
Duffusion → the process by which molecules spread from areas of high concentratiion, to areas of low concentration
Pulmonary Respiration → ...
Expiration → diaphragm relaxes & moves up into original dome shape. This decreases the chest volume & moves air out of the lungs
