<unk> ing effect of a projectile is produced by transfer of Kinetic Energy (KE) from the projectile to the tissues
Projectile does not exit the body then all its kinetic energy has been transferred to the tissues
Projectile that exits the body then only some of its KE has been transferred to the tissues<unk> ing effect is the result of the amount and location of crushed and stretched tissue from this KE transfer
The greater the KE the greater the<unk> ing potential

Permanent cavity - The hole left by the passage of the projectile is proportional to the size of the projectile. This is the volume of space once occupied by tissue which has been destroyed.
Cavity is a function of the penetration and frontal area of the projectile which makes it.
Cross-sectional area of the projectile track is comparable to the presenting area of the projectile and its dimensions are roughly the same for all soft tissues
Size of the permanent cavity can be increased by yaw (deviation of bullet from straight path within tissue). As more tissue is in contact with projectile there is more tissue damage
Size of permanent cavity can be increased by projectile deformation and fragmentation as well.
Deformation is when a projectile changes it shape upon contact with tissue which increases the diameter of the projectile. The flattening or deformation can cause 4 to 6 times greater tissue contact thus more tissue damage. Example<unk>  be hollow point bullets.
Fragmentation is when a projectile breaks apart within tissue creating many smaller projectiles. Fragmentation is more devastating than deformation.
Temporary cavity - The transient expansion of the permanent cavity by stretching due to the transfer of KE during the projectiles passage. The walls of the permanent cavity are temporarily stretched radially outward.
Temporary cavity may be up to thirty times the diameter of the projectile with a lifetime of 5 to 10 milliseconds with pressures of up to 100 to 200 atmospheres
Damage is due to stretching of the tissue
Damage is analogous to localized area of blunt trauma surrounding the permanent cavity
If the pressure of the temporary cavity exceeds the elastic limit of tissue then the organ may be disrupted "burst" or "fractured" and a large permanent cavity may be seen. Dense organs which are relatively inelastic are most susceptible to this affect (i.e. liver) whereas organs with low density and high elasticity are relative protected (i.e. lung).
