Text Solution
Verified by ExpertsThe correct answer is:
The movement of air into and out of the lungs is carried out by creating a pressure gradient between the lungs and the atmosphere. The pressure within the lungs is less than the atmospheric pressure so there is a negative pressure in the lungs with respect to atmospheric pressure.
The puncture in the chest affects this pressure gradient maintained by the lungs and thus may cause cessation of breathing.
