Note
Kinship by birth usually travels in set phrases: related by blood, of our own blood, or Walter Scott's "the blood of Saxon royalty" in Ivanhoe. Background, descent and stock are near synonyms. Blood, however, pictures inheritance as something carried in the body, which is why it can be imagined to speak. "Listen to the voice of your blood," one character urges in Star Trek: The Next Generation. Heritage rarely talks back like that.

Similartemper, temperament, spirit, passion
Note
Temper here keeps its old sense of a mixture. In Julius Caesar, Cassius speaks of "greefe and blood ill temper'd," and in Henry IV, Part 2 a man's blood is "inclined to mirth." The idea comes from the humoral theory, in which the balance of bodily fluids set one's mood. Mirth and grief both qualify, so the sense is not limited to anger.

Note
A term of solidarity in African-American Vernacular English and in British street slang, where the spelling blud came in through Jamaican speech. It can name a friend (my blood from back home) or address one directly (What's good, blood?). Its warmth comes from the kinship sense: a friend is spoken of as family. Because it signals belonging, it sounds most natural among peers who already share it.
