my comment is for the topic that was being discussed before all of the children got out of school and decided to call each other names.
There are three types of blood vessels in the human body. They are veins, arteries and capillaries. Veins carry blood to the heart. Arteries carry blood away from the heart. Capillaries are the small blood vessels that branch out and carry blood to the cells/tissue.
The only blood vessel that can be severed that will result in spraying blood is an artery. It carries blood away from the heart. The heart is pumping the blood through the vessel thus being pressured/forced. If you do cut open an artery, the blood that is being forced through the artery by the heart will indeed spray out. The faster the blood is moving through the vessel (depending on the person's heart rate), the faster/further it will spray.
You have arteries running from your torso to all of your limbs and head. You do not however have arteries running to the appendages attatched to the end of the limbs (fingers/thumb/toes).
In Freddy vs. Jason.........Freddy slices Jason's fingers off while he is holding his machete. Blood starts squirting out. This is obviously ridiculous for the reasons I just mentioned. Englund even makes fun of this in the dvd commentary.
To sum it up: Yes....the movie is anatomicly/physicly inaccurate.........but who cares? It was not made to be an anatomical documentary.........it's a slasher movie......emphasis on SLASH. When we see slashes....we want to see blood resulting from the slash. They tried to deliver the most blood they could.
