Flashcards in Chapter 27 - Trauma Overview Deck (10):
1

cavitation

a cavity formed by a pressure wave resulting from the kinetic energy of a bullet traveling through the body tissue; also called pathway expansion.

2

dissipation of energy

the way energy is transferred to the human body by the forces acting upon it.

3

drag

the factors that slow a projectile.

4

fragmentation

the breaking up of a bullet into small pieces on impact.

5

kinetic energy

the energy contained by an object in motion. Kinetic energy equals mass (weight in pounds), times the velocity (feet per second) squared, divided by two.

6

kinetics

the branch of mechanics dealing with the motions of material bodies.

7

kinetics of trauma

the science of analyzing mechanism of injury.

8

mechanism of injury (MOI)

the factors and forces that cause traumatic injury.

9

profile

the size and shape of a bullets point of impact; the greater the point of impact the greater the injury.

10

trajectory

the path of a projectile during its travel; a trajectory may be flat or curved.
