...successively into bronchioles, air ducts (ductuli alveolares), air pockets (atria), lobules. Lobules bulge with many air sacs (acini) which look like clusters of grapes. Walls of the lobules adjoin walls of capillaries in which the pulmonary veins and pulmonary arteries terminate. The pulmonary arteries bring dark blood loaded with carbon dioxide from the body's tissues to the lobules. The lobules treat the blood with fresh oxygen, leaving it pure and crimson...
Physiology involved depends on the acid-alkaline condition of the body. Exertion causes the oxidation (burning) of blood sugar in the muscles. Product of that combustion is lactic acid which ordinarily changes into carbon dioxide and is exhaled. During intense effort too much lactic acid is produced in a short time to be eliminated (as oxidized gas) through the lungs. This causes trouble unless the blood contains enough alkaline substances to neutralize the acid. Oranges, grapefruit and lemons alkalinize the blood in a natural way. So do certain mineral waters. But none, according to Berlin's Professor Dennig...
