Answer to Question 1

The two major disturbances are called cardiospasm, which is the failure of the cardiac sphincter to open properly, and incompetent cardiac sphincter, which is the inability of the sphincter to remain properly closed. This latter condition can lead to a condition called reflux esophagitis.

Answer to Question 2

Ventilation is impaired if the nerve supply to the respiratory muscles is damaged by disease or if the respiratory muscles undergo atrophy and degeneration. Ventilation is also impaired if the thoracic cage is immobile.

There can actually be a 25-hour time difference between certain locations in the world. The International Date Line passes between the islands of Samoa and American Samoa. It is not a straight line, but "zig-zags" around various island chains. Therefore, Samoa and nearby islands have one date, while American Samoa and nearby islands are one day behind. Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.
