How destroys the blast?

The shock wave is a rapid rise in atmospheric pressure caused by the release of energy that takes place at the sudden transformation from solid to a gas explosion.

To penetrate the body, the shock wave subjected to corporal viscera to a high overpressure and a violent displacement.

This causes the rupture of the surface of dense materials, such as gastrointestinal or the alveolar wall.
In addition to the damage in such areas, the water glasses that these organs burst, causing severe internal bleeding.

Moreover, the passage of the wave causes the tissues to move at different speeds depending on their density, causing severe damage to them.
