A blood seems blue in veins because when a blood is in veins they are low in oxygen and therefore look blue. When they get oxygenated, they become red and are carried by the artery.
No-one really knows.

Your aunts and uncles are the sisters and brothers of your parents. So they are "blood related." But you also call the husband of your mother's sister your uncle, and he is not "blood related." So aunts and uncles are not always really related to you.
Red= The armymens blood from the war, White= Courage from the armymen and Blue= Justice from the armymen because they won the war!!

There are several animals that are said to have blue hearts or blue blood. These are worms, squid, and octopuses. They do not really have blue hearts, it is just the color of the blood in the body before reaching the air.
