It enters the blood in the capillary circulation from the tissues in which it is formed. The gases occurring in the blood under ordi- nary physiological conditions are oxygen, car- bonic acid, and nitrogen. The latter is present only in minute quantity and seems to play no important role in the vital processes, its quan- tity in different parts of the circulation being approximately the same. The amounts of oxygen and carbonic acid present differ, not only in the blood derived from various parts of the circulation, but also in their correspondence to the rapidity of the blood-current, the different temperatures, rest, labor, etc. According to Setschenow, oxygen is con- tained in the arterial blood of man to the amount of 21.6 per cent, by volume. The amount carried by the venous blood differs. Ludwig and Szeltcow found 6.8 per cent, of [2]
