C. ​"Did the knife penetrate your chest​ easily?" D. ​"Was the knife clean or​ dirty?"

A. ​"How long was the knife​ blade?"

Why is the exit wound of a bullet always larger than the entry​ wound? A. When the bullet enters the​ dermis, it breaks into many small pieces that travel in different directions. As these bullet pieces pass out of the​ body, they destroy a wide path of tissue. B. As the​ bullet's energy dissipates into​ flesh, its kinetic energy is transferred to the tissues. This causes exit wounds that are much larger than entry wounds. C. As the bullet enters the​ skin, it flattens​ out, or​ "mushrooms," increasing its surface area.​ Thus, when it exits the​ body, it displaces more tissue than it did when it entered. This creates the larger exit wounds. D. As the superheated metal of the bullet proceeds through the​ skin, it burns away all tissue that it touches. The heat destruction radiates into a tubular shape along the trajectory of the​ bullet, causing the​ bullet's exit to be larger than its entrance.

B. As the​ bullet's energy dissipates into​ flesh, its kinetic energy is transferred to the tissues. This causes exit wounds that are much larger than entry wounds.
