because blood/spit contains cells
in an open ciculatory system, the oxygented blood and the un-oxgenated blood mix, sending various amounts of both around the body. while in a closed one, the oxygenated blood and un-oxygenated blood are kept seperate(making sure that the body is always getting the best blood and is rejuvinating the bad blood)

The term "impure blood" is not medical in nature. The only context in which I've heard it used is when racist people refer to anyone whose ethnicity is different from his or her own as having "impure blood". So, in the eyes of the people who actually use this term, being born to the wrong parents causes impure blood. Sometimes "impure blood" can mean the deoxygenated blood that the veins transport from the rest of the body to the heart as opposed to the oxygenated blood that arteries transport from the heart to the rest of the body. In fewer words, "impure blood" is a term that can be used to refer to blood without oxygen.
