The Short Answer
This is caused by what is known as the vasovagal response. It's a reaction by the body to certain triggers that causes the heart rate and blood pressure to drop, which in result causes you to feel lightheaded and queasy because the brain doesn't get enough blood. One of the thoughts is that it is an evolutionary mechanism to prevent blood loss when the body is considered in danger, as a lower heart rate and blood pressure slows down blood loss. The strength and triggers of this reaction differs in different people, where for some people the mere sight of blood causes the reaction.
