    • n blood The fluid which circulates in the arteries and veins. From it the solid tissues take their food and oxygen, and into it they discharge their waste products. The blood is red in vertebrates, except amphioxus, and colorless, red, bluish, greenish, or milky in other animals. In passing through the lungs (see circulation) it is oxygenated and gives up carbon dioxid; then, after passing through the heart, it is carried as arterial blood by the arteries to the tissues; from the tissues it is returned to the heart through the veins, deprived of its nutrient properties, as venous blood. The venous blood of the Craniota is dark-red, the arterial bright-scarlet. The specific gravity of human blood in health is about 1.055. The blood consists of a fluid pale-yellow plasma and semi-solid corpuscles; the latter constitute between one third and one half of it; they are of two kinds, red and white. In a cubic millimeter of healthy human blood there are about 5,000,000 corpuscles, the red being to the white on the average about as 350 to 1. The red corpuscles are flat biconcave disks, non-nucleated and almost always round in mammals, and nucleated and almost always oval in other Craniota. Their diameter averages in man about 7.5 micromillimeters ( inch), while in Amphiuma tridactylum the longer diameter is 67.2 micromillimeters ( inch). Their color is due to hemoglobin, which constitutes about 90 per cent. of their dried substance. The white corpuscles are nucleated, slightly larger than the red in man, and exhibit active amœboid movements. Animal blood is used in clarifying sugar, in making animal charcoal, as a manure, and in many other ways.
