Final answer:
Pulmonary hemorrhage and inner ear damage are directly caused by overpressure waves from an explosion, categorizing them as primary blast injuries that impact air-filled organs.
Step-by-step explanation:
Pulmonary hemorrhage and inner ear damage are examples of primary blast injuries. These types of injuries occur as a direct result of the overpressure waves from an explosion. Primary blast injuries predominantly affect air-filled organs, such as the lungs and the auditory system.
Specifically, pulmonary hemorrhage refers to bleeding within the lungs, which can be caused by the high-pressure shockwave disrupting blood vessels. Moreover, damage to the inner ear structures, including the tympanic membrane and cochlea, often occurs due to their sensitivity to pressure changes.
