Cavitation - firearm

Cavitation
* A bullet🔫 fired from handgun (e.g. pistol and revolver) has low ⬇️velocity, so has low KE 🔥and so damage is less and confined to the wound track.
A bullet having very high velocity (e.g. military rifle) crushes and shred the tissues in its path as well as produces a fusiform cavity ♉️far wider than the diameter of the bullet.
This cavity reaches a maximum size within milliseconds and then pulsates with decreasing amplitude. It results from temporary tissue 🥓displacement centrifugally outwards following bullet passage.
Since this cavity persists temporarily for 5-10 ms, it is k/a temporary cavity and the phenomenon is k/a temporary cavitation.
When the bullet leaves the organ, the temporary cavity rapidly subsides, but the track of damage persists in a tubular zone.
This tubular zone of damaged tissues is k/a permanent cavity and the phenomenon is k/a permanent cavitation.
The near vacuum developed behind the bullet sucks infected 💩dirt and clothing fibres into the wounds.
The phenomenon of cavitation affects solid organs, 🧠🦝for example liver, brain more as compared to spongy tissues, for example lungs.
