How do a bullet from gun destroys human body?

A bullet from a gun can cause significant damage to the human body, and the severity of the damage depends on a number of factors, including the caliber of the bullet, the velocity of the bullet, and the point of impact.

When a bullet enters the body, it creates a temporary cavity that is much larger than the diameter of the bullet itself. This cavity is caused by the shock wave that is created as the bullet travels through the body. The temporary cavity can cause damage to the surrounding tissues and organs, and can also cause blood vessels to burst.

In addition to the temporary cavity, a bullet can also create a permanent cavity. This cavity is caused by the actual tissue that is destroyed by the bullet. The permanent cavity can be much smaller than the temporary cavity, but it can cause more serious damage, as it can involve damage to vital organs and blood vessels.

The point of impact of the bullet is also an important factor in determining the severity of the damage. A bullet that strikes a vital organ, such as the heart or the brain, is more likely to cause serious injury or death. A bullet that strikes a non-vital organ, such as the arm or the leg, is less likely to cause serious injury.

In some cases, a bullet can also cause ricochets, which are when the bullet bounces off of a surface before continuing on its trajectory. Ricochets can cause similar damage to that of a direct hit, and can also be unpredictable.

Overall, the damage caused by a bullet from a gun can vary depending on a number of factors, but it is always important to seek medical attention if you have been shot.
