The Worst of Conditions - S2-E3
Factual error: The Seal team is heading up the stairs and a terrorist pokes his head out, and he gets shot 4 times with 5.56 rounds. He's dead, but he manages to exhale a grunt and as he's falling down the middle opening of the stairwell, and he's screening "ahhhhhhhh." This show and many like it have found a need for dead guys to exhale grunts or screams. When somebody is killed their brain shuts down. There's no noise being made by the body unless it's the body itself falling like a sack of potatoes. (00:41:00)
Answer: Depending on caliber the body does spray blood from .308 and up.
