How Does Dracula Suck Blood? :THE MECHANISM

This one's a bit scientific.. ;)
Have you pondered over that how does DRACULA suck blood with his long….scary canine teeth??
This is one difficult question I think as nobody has ever disclosed this mechanism…. Or has somebody done it already???
Well, I am not aware of… if it has happened already….

Cheshta's First Theory on Blood Sucking Canines
According to my theory, as we all have seen the DRACULA named organism just putting his teeth into the skin and then sucking the blood with his canines. Also as he never sucks through his mouth, there is for sure something fishy about his teeth!!!
I suppose there are apertures at the tip of the teeth connected to some teethic ducts through which the blood goes into his body.. Using this horrific mechanism he sucks the blood of his prey and thus, kills them.. Or else

Cheshta's Second Theory on Blood Sucking Canines
According to this theory, it is supposed that Dracula has a suction pump-type mechanism in his body because of which blood is absorbed in his body… huh.. Bad bad Dracula…. The main thing is that I have not been able to prove any of my theory because till date no Dracula has volunteered for the dissection experiment that I wanted to carry out…. Instead, they have warned me lot many times you-know-what-for. So, I cannot say 'Hence proved' to any of the theories.

Through this blog, I want to create an awareness and want people to come up with their theories (or hypotheses), so that we may reach a conclusion and finally devise a mechanism universally accepted(can be possible we even come across a vampire…. Heeheehaahaha) …!! So…people c'mmon…this world needs you..!! ;)
