They aren't; they are white.
The cells in the bloodstream include red blood cells, white blood cells, and platelets. Red blood cells carry oxygen to tissues, white blood cells help fight infections, and platelets aid in blood clotting.
White blood cells have a nucleus and red blood cells don't.

There are no blue blood cells. Blood cells are either red cells or white cells. Red cells are a very pale red when seen individually, but make blood look red when there are millions of them together. White blood cells are actually colourless. They are stained with various stains to make then visible under the microscope. See http://www.kidshealth.org/parent/general/body_basics/blood.html http://en.wikipedia.org/wiki/BloodBlue blood cells are cells that are not oxygenated. In other words, blood that runs through your body that have not reached oxygen take the color of blue.
Another name for white blood cells are " Lymphnoytes"
No. There are no blue blood cells. There are only white blood cells (lymphocytes) and red blood cells(erythrocytes).
Yes, except for the blue. It's a human, not the flag.
No, only red and white.
In relation to the human body, it is a common misconception that blood is blue; all blood is red. The blue appearance is due to the connective tissues of the blood vessels. Blood cells can be either erythrocytes, which are red, or leukocytes, which are white. When blood is oxygenated it is a much brighter red than de-oxygenated blood.
The white blood cells
Red blood cells contain hemoglobin, but white blood cells do not
De-oxygenated human blood is NOT blue. Blood in veins is NOT blue. Human blood is ALWAYS red regardless of whether it is venous or arterial blood, regardless of whether it is oxygenated or deoxygenated, regardless of whether it is inside the body or outside the body. Human blood is red. Period. Veins appear blue from outside the skin because of the way light interacts with skin and blood - NOT because blood is blue in color.

White blood cells fight infection while the red blood cells carry blood to your heart.
