Blood is the red fluid that circulates through the body by way of the blood vessels. The adult human body contains between 5 and 6 quarts of blood, weighing about 7 to 8 pounds and accounting for about 5% of the body weight. If about one-third of the blood is lost, death usually occurs (unless the blood is replaced). A pint of blood, however, can be readily spared at proper intervals. Blood in the arteries is bright red in color; blood in the veins is much darker, sometimes a brownish red.
