A number of things would happen if you inject human with horse crab blood. This used by the pharmaceutical for various reasons including getting rid of ecoil. It may cause fever and other types of responses as well.
No, they need human blood.
Well, although there are different ways for different books, the general idea is that you have to be bitten by a vampire, and then after they've fed from you they will "inject" you with their vampire blood. Then you will die due to the bite and the loss of blood, etc, but then once you've woken up you will be a vampire, as you had been "injected" with vampire blood. Sometimes this doesn't always happen though, sometimes vampires only drink from you lightly, maybe leaving you a little faint, or they could just drink from you and not inject their blood into you, therefore leaving you to just die.
There may be issues
well, if you inject the same blood into the same human that you took the blood from it wont do anything. inless the blood was cold and hasent been properly handold. then the blood will start to clot up in the body and slowly kill the person inless he is sent to the hospital....
The body would die.
They would EXPLODE
No human endeavour could make or inject magma into a volcano. The magma found in relation to volcanoes is a natural phenomena.
They are diseases that happen within your heart, and blood vessels.
moquitos inject a chemical that prevents blood from clotting when they suck it up. this chemical is an irritant to the human immune system, which causes redness and itching. They are not posionous.
I doubt it would. If it did it would be a physcotic butterfly...
The Duckbill Platypus is an interesting animal. Did you know that the males have stinger behing one of their back legs and can kill a human with the poison that they inject. Doesn't happen often, but it happens.
They ate grains, fresh fruit, horse meat, and fish. They drank milk and the blood of a human. :-(
