The fluid which circulates through the heart, arteries, veins and capillaries of vertebrates. Blood contains plasma, blood cells, and platelets. It transports oxygen and nutrients to the bodies tissues and carries away waste substances. Because blood coagulates and becomes insoluble when exposed to air, it has been used as an adhesive (see blood glue) and paint binder since ancient times. Dried animal blood has also been used for fertilizers and as a nutrient.
