When the muscle relaxes the two layers tend to be drawn apart, thus causing a sort of vacuum into which the juice containing the products of waste is sucked out of the muscle. Thus it is that muscles in Fig. 7. Diagram of transverse section of voluntary muscle to show tlie pumping action exerted on tlie muscle, juice and waste products during action. The blood-vessels cross diagonally. To the left (b) the muscle is contracted and presses the two layers of the fascia together so as to drive the muscle juice out into the lymphatics. To the right (a) the muscle is relaxed and tends to draw the layers of fascia apart and suck the juice out of the muscle into the lymph space, c, Artery, d, Artery, e, Lymphatics. /, Vein, g, Vein. The double arrows in (a) are intended to indicate the increased blood flow through the muscle, and the single arrow within the muscle to indicate the passage of fluid from the muscle into the lymph space between it and the surrounding fascia. the healthy body will go on acting for hours together without showing the least sign of fatigue. Moreover, the constant removal of the waste tends to bring about a freer supply of blood, with fresh nutriment, just as we almost invariably have to put fresh coal on a fire after we have raked out the ashes. Thus it is that constant exercise of the muscles, instead of making them become smaller, increases their bulk and strength, and the body
