Blood is a body fluid in humans and other animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells.
Science (from Latin scientia, meaning "knowledge") is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.
I have often noticed that ancestors never boast the descendants who boast of ancestors I would rather start a family than one blood will tell but often it tells too much
Don Marquis, archy and mehitabel (1927), a roach of the taverns, p. 156–57.
So ye shall not pollute the land wherein ye are: for blood it defileth the land: and the land cannot be cleansed of the blood that is shed therein, but by the blood of him that shed it.
