|
|
diaphragm pushed up, internal pressure |
increased |
|
|
diaphragm pulled down, internal pressure |
decreased |
|
|
size of balloons (lungs), diaphragm pushed up |
decreased |
|
|
size of balloons, diaphragm pulled down |
increased |
|
|
direction of air flow, diaphragm pushed up |
out of lungs |
|
|
direction of air flow, diaphragm pulled down |
into lungs |
|
|
under what internal conditions does air tend to flow into the lungs? |
increased thoracic volume, and decreased pressure |
|
|
under what internal conditions does air tend to flow out of the lungs? |
decreased thoracic volume, increased pressure. Gases move in the direction that tends to equalize pressure inside and outside the "container" |
|
|
which of the respiratory sounds is heard during both inspiration and expiration? |
bronchial |
|
|
which is heard primarily during inspiration? |
vesicular |
|
|
where did you best hear the vesicular respiratory sounds? |
heard over most of the lung area |
|
|
volume of air present in the lungs after a forceful expiration |
residual volume (~1100 ml ) |
|
|
volume of air present in the lungs after a forceful expiration: |
expiratory reserve (~1200 ml) |
|
|
volume of air that is breathed in and out during a normal respiration: |
tidal volume (~ 500 ml) |
|
|
volume of air that can be inspired forcibly after a normal inspiration: |
inspiratory reserve (~ 2700 - 2800 ml) |
|
|
volume of air corresponding to TV + IRV + ERV: |
Vital capacity (~4800 ml) |
|
|
where are the neural control centers of the respiratory rhythm: |
medulla oblongata and pons |
|
|
which respiratory ailments can respiratory volume tests be used to detect? |
chronic bronchitis and emphysema. Chronic bronchitis decreases the volume of air that can be inhaled due to excessive mucus production; emphysema decreases the amount of air that can be exhaled (check valve effect) |
