From the question they given us a person is going to fall and break his ribs.
00:15
Due to breaking of ribs it causes the puncture of pleural cavity.
00:26
This lead to, we have to identify the what are all the changes of pressure to be taken place when the puncture of pleural cavity takes place.
00:40
We have to identify first the characteristics of the pleural cavity.
00:44
Therefore the characteristics of pleural cavity was found to be a, first it's going to regulate the pressure.
00:55
During exhalation the pleural cavity pressure is going to be increased.
01:03
During inhalation the pleural cavity pressure is going to be decreased to about negative value.
01:17
Therefore when the puncturing of pleural cavity takes place, damage to the pleural cavity takes place.
01:29
In this condition during damage of pleural cavity at exhalation condition there will be a pleural cavity with decreased pressure which is about negative value as the pleural cavity was damaged.
02:00
It causes the expansion of lungs can be affected.
02:12
This means a lungs can't expand because a pleural cavity pressure is decreased therefore exhalation is affected.
02:26
A lungs can't expand during this condition...
