The stomach rests, while the involuntary absorptive functions continue their work, even upon excreted tissue waste ; and, lest harm result, the most expeditious mechanical means must be employed to remove this product from the digestive tract. The blood, following its mission, gathers the refuse from cell structure, and supplies for rebuilding purposes what it finds available. This it discovers in the reserve supply of nourishment naturally stored in the interstices of tissue. As the process of elimination or purification continues, waste grows less; the density of the blood is reduced gradually, as refuse diminishes in quantity; and the labor of the heart is thus progressively lightened.
