This question has been answered many times in this thread, so I suggest you simply read it from the start
Open mouth, pour blood in mouth (or suck it in), swallow.
As for the other question, I suggest rewording/developing/spell checking to make it understandable if you want an answer.

any proof. (Ashley Montague)
(sighs) being a biology student in grade 10, I too beleived at first that the colour of venal blood is blue, besides, i don't think it has anything to do with genes. Venal blood is dark red in colour. You see, it's basic physics which leads us to the distortion of light. The blood in the veins absorbs the red colour from the light ( the light here is diffused by the skin) and reflects the blue colour. Therefore, we get a certain blue tinge.
Well it is due to Hemoglobin present of blood. Also iron-haem group is present at the center of each haemoglobin molecule which absorbs light in the blue portion of the spectrum, leaving a red colour.
Mistakes are the portals of discovery.
Actually, when blood is not oxygenated, (hasn't passed through the lungs), it IS blue. It's the reaction with nitrogen in the air that makes it red, which is why when you get a cut, or when it passes through your lungs, it's red.
There is a tribe in Africa that lives on blood and milk. They raise cattle, and get both from their livestock.
