Dude, they have to take blood out of your penis with a needle.. Go to your doctor, you can become blind with not enough blood to your eyes, i am serious.
It is impossible to become a vampire, if you drink blood your stomach will not be able to digest it, you have to go to the doctor, they take out the blood, then they'll give you the hospital bill. Plus vampires are just stuff Hollywood directors made up. sorry. :|
this is two step process.in the first process blood go from the heart and in the second step blood come into the heart for clean. when it goes from the heart it is cleaned blood,but when it returns it become dirty and our heart performs as a filter and it cleans our blood. this is the chemistry of blood, hopefully you would like it.
totally, if a vampire takes SOME blood the human will turn in to a vampire. If the vampire takes ALL the blood the chances are most likely to go in to a coma and eventually die.
Because they are dead, their hearts do not bump blood around the body, so they drink human blood. Some vampires do this in different ways though - some just go around murdering people while others give humans the option to die or to become a vampire. Either way if they do not drink blood, they soon become weak, fragile creatures.
When it is rich with oxygen. It will become dark colour when it contain less oxygen (after the oxygen used by the body tissues )
You don't go near one in the beginning. Or dont cut yourself and let the water become red with blood.
To become a vanpire u must get your blood sucked by one. This is how when you a bat go to it then it will suck your blood. Then you are a vanpire. But you can't see your family because if you see a human you will bite them.
It changes because your blood stops flowing causing your skin to become pale. You blush when you're nervous because your blood starts flowing-alot and you go pale when you die.
The swelling would go down and the pain would become less. Blood flow would also become better and that would help the healing process.
