[split] Vampires and Vampirism

['thul]

in those books described above, they still have operational circulatory systems, as well as several other bodily systems... The vampires reaction to human food is like a human's reaction to eating grass. It is quite possible, but also pointless, since the body does not have the means to gain nourishment from it. It is more common in vampire lore for human foods to be directly dangerous to vampires, but this series chose another path. (examples of poisonous reaction: let me in; Underworld)
It would appear that L.J.Smith vampires have fully functional bodies, with all systems operational aside from a few minor changes... they heal extremely fast, they can only get nourishment from blood, they can on occasion move with lightning speed, and their senses are enhanced. Otherwise, their bodies are like humans. (oh, and they burn in the sun)
