Circulation

Life is the end (product) of digestion ... The body is composed of cells and their products ... each cell leads to a certain extent an independent existence ... the individual life of (each) cell is related to the life of the organism as a whole. page 36

Capillaries alone cover every part of the body ... neither arteries nor veins are minute enough ...so infintestimal ... that a thousand ... may be counted in a square inch of flesh ... permeating the solid structures ... supplying food materials for the walls of veins and arteries ... they reach everywhere and carry food, water, and oxygen to every cell. Normal function and normal correlation of function, indeed, life ... rests upon a normal "internal environment" ... maintained in the organism ... by the exercise of its nutritive and excretory functions ... provid(ing) ... nutriment ... sweet(ness) and clean(liness) ... conditon(s) essential to continued existence.

Viewing the complex organism, we see that the vast majority of its cells are ...barred from contact with the sources of food, water, and oxygen and cannot expel their waste ... (as does the one-celled organism) ... nutritive materials must be brought to them and their waste carried away. It is not enough for the digestive tract to prepare nutrients ... (nutrition) much be brought into contact with the cells.

To this end all complex organisms are possessed of means of circulating the fluid medium in which their cells live. page 39

Circulation depends, for its highest efficiency, upon muscular activity, so that exercise in some form becomes an essential of vigorous and continued health. Invalids need exercise as much as the well. Exercise is essential to the development and maintenance of vital structures ... the sick ... often need special application of exercise to meet special requirements. page 44
