Blood \Blood\, n. [OE. blod, blood, AS. bl?d; akin to D. bloed,
   OHG. bluot, G. blut, Goth, bl??, Sw. & Dan. blod; prob. fr.
   the same root as E. blow to bloom. See {Blow} to bloom.]
   1. The fluid which circulates in the principal vascular
      system of animals, carrying nourishment to all parts of
      the body, and bringing away waste products to be excreted.
      See under {Arterial}.

   Note: The blood consists of a liquid, the plasma, containing
         minute particles, the blood corpuscles. In the
         invertebrate animals it is usually nearly colorless,
         and contains only one kind of corpuscles; but in all
         vertebrates, except Amphioxus, it contains some
         colorless corpuscles, with many more which are red and
         give the blood its uniformly red color. See
         {Corpuscle}, {Plasma}.

   2. Relationship by descent from a common ancestor;
      consanguinity; kinship.

            To share the blood of Saxon royalty.  --Sir W.
                                                  Scott.

            A friend of our own blood.            --Waller.

   {Half blood} (Law), relationship through only one parent.

   {Whole blood}, relationship through both father and mother.
      In American Law, blood includes both half blood, and whole
      blood. --Bouvier. --Peters.

   3. Descent; lineage; especially, honorable birth; the highest
      royal lineage.

            Give us a prince of blood, a son of Priam. --Shak.

            I am a gentleman of blood and breeding. --Shak.

   4. (Stock Breeding) Descent from parents of recognized breed;
      excellence or purity of breed.

   Note: In stock breeding half blood is descent showing one
         half only of pure breed. Blue blood, full blood, or
         warm blood, is the same as blood.

   5. The fleshy nature of man.

            Nor gives it satisfaction to our blood. --Shak.

   6. The shedding of blood; the taking of life, murder;
      manslaughter; destruction.

            blood atones.                         --Hood.

   7. A bloodthirsty or murderous disposition. [R.]

                                                  --Shak.

   Note: Often, in this sense, accompanied with bad, cold, warm,
         or other qualifying word. Thus, to commit an act in
         cold blood, is to do it deliberately, and without
         sudden passion; to do it in bad blood, is to do it in
         anger. Warm blood denotes a temper inflamed or
         irritated. To warm or heat the blood is to excite the
         passions. Qualified by up, excited feeling or passion
         is signified; as, my blood was up.

   9. A man of fire or spirit; a fiery spark; a gay, showy man;

   10. The juice of anything, especially if red.

             He washed . . . his clothes in the blood of grapes.
                                                  --Gen. xiix.
                                                  11.

   Note: Blood is often used as an adjective, and as the first
         part of self-explaining compound words; as,
         blood-bespotted, blood-bought, blood-curdling,
         blood-dyed, blood-red, blood-spilling, blood-stained,
