ELI5: What happens internally when someone gets shot? What really kills someone?

I've been watching Westerns all day, and I've become curious about what happens when a bullet enters the body. Do organs rupture? Is there massive internal bleeding? What makes the difference between someone living and dying?

Thanks ELI5!

1) entrance wound, source of blood loss

2) permanent bullet path, a corridor of destroyed tissue usually a little wider than the bullet

3) temporary wound cavity, splash effect expands an area for a split second (banana to football sized) the organs in this area rupture, the blood vessels thrombose (clot up and stop working)

4) Hydrostatic shock may occur, where the wound channel sends a shockwave of pressurized blood through the system causing immediate loss of cosciousness or death.

5) bones are broken and parts of these bones fly througout your body creating many smaller wound paths

6) exit wound, a source of blood loss

7) material such as clothing and dirt is sucked into the collapsing wound path leading to infection.

roughly 80% of people shot in the torso with a handgun live

roughly 20% of people shot in the head with a handgun live

People rarely die quickly or quietly.
