Hi, please consider this answer :
LIFE is closely associated with blood. It is the blood that transports needed nourishment and oxygen to all parts of the body, and carries away the waste products. Blood being so intimately involved in the life processes, the “soul” or life of a creature is referred to in the Bible as being “in the blood.”—Lev. 17:11.
Since life is sacred, blood is also sacred. Respect for the sanctity of blood is therefore respect for life. The Giver of life, Jehovah God, has laid command upon mankind to respect life, including that of animals. When he permitted Noah and his family to add flesh to their diet, he stated: “Every moving animal that is alive may serve as food for you. As in the case of green vegetation, I do give it all to you. Only flesh with its soul—its blood—you must not eat.” (Gen. 9:3, 4) Having descended from Noah through his three sons, all of us are under that command.
