i have a Biology lab and i have no clue about these questions... help please :P

1. Why can we here vesicular breathing more clearly under the arms while bronchial breathing is heard more clearly between the shoulder blades?

2. What differences did you detect betweent the sounds heard during quiet breathing and breathing after more strenuous activity?

3. How does your calculated vital capacity compare to your recorded vital capacity? how would you explain the difference?
(Vital capacity: 300 cm3) Calculated
(Vital capacity: 1700 cm3) Recorded

Thanks sooo much!!
