Biology of Vampires

[xPANICxITxISxJANEx]

No, I'm not talking about the Biology scene from Twilight >.< I'm talking about the actual biology of vampires.
Here's what it is:

Vampires are created when humans are bitten by other vampires who have teeth coated in venom. Venom is spread throughout the human's body. The venom consumes the blood and replaces their blood with venom turning him/her into a vampire. Vampires probably started when a chemical of unknown substances (the venom) was found and injected into the body.
The venom feeds off of blood by disinegrating the blood. Imagine your stomach and the stomach acids that eat off the food? The "stomach acids" could be an example of venom except they ONLY disinegrate blood.
Since these vampires do NOT have fangs, the blood they drink travels down their throat where the venom is. The traditional vampire (w/ fangs) drinks blood through their fangs. The blood would travel in their fangs to (maybe) another organ that requires blood to live. Those types of vampires can still eat food. Twilight vampires do not have an extra organ.
Vampires do not eat food. When they swallow it, they cough it back up. The venom rejects the food but not right away.
Vampires shine in the sun most likely because their venom contains a substance that reflects light rays and cause the body to shine.

Helpful? Wondering about something else? Just post in this thread :3
Of course, I don't know everthing. Most of these are guesses.

I think most of this stuff is addressed at some point or another between the personal correspondences and Stephenie's website.

Here are some more biology facts:

1. Vampires don't have just one kind of venom; they have many, many kinds, and each one serves a very specific function. For example, they have one kind of venom in their eyes that lets their eyeballs move around in their sockets, and another kind that lubricates all the body cells, and another kind that transforms other humans into vampires, and many more.

2. The reason vampires smell so good to humans is because the blood they drink is transformed by their bodies into a sweet perfume that is secreted from the skin for the purpose of attracting humans.

3. It's the skin itself that makes them sparkle in the sunlight, not venom on the skin.

there are still some things that dont make sense.

if a vampires heart doesnt beat, then how could male vampires get erections? therefore sex would be impossible, yet twilight vampires certainly have their fair share of it.

also the strength. if the vampires are simply "toned" as stephanie put it, they wouldnt have enough muscle to be able to run so fast or be so strong. they would have to be like 3x arnold sized for that to work.

not trying to spoil the idea of vampires or anything (god knows id do anything to become one) just some parts dont line up... emo

venom makes vampires stronger and I don't think it tones out their muscles.
And as mentioned above, there are different types od venom. The venom in the heart must be different from the rest of the venom which cause them to have feelings. But they can't cry because of the venom in their eyes (that venom sharpesn their eye sight) stop the tears from falling out. In Breaking Dawn, Bella mentioned while a vampire that when she thought she would be crying, it was burning...or something like that

The skin must be affected in some way by the venom to cause them to shine.

that still doesnt answer my sex question... lol  

[VampirePrincessOftheNorth]

With their theory of the venom for a vampire there must be a venom that allows a vampire to have sex.

Also I would like to ask the author to please specify that this is twilights take on the biology of vampires because this is extremely different from the real vampires that are coexisting with the humans today.

Thanks

Most of it is not confirmed by Stephenei Meyer. Most of it is asumed from what you can learn from the books and extras that were released by the author of the Twilight Saga.
