Webdecomposition rates are high at high temperatures, provided that enough moisture and oxygen are available for decompo-sition. Furthermore, we found that decomposition rates are mostly limited by oxygen concentrations at high moisture levels; even at 90% WFPS, decomposition proceeded at high rates in the presence of oxygen. Our results suggest ... WebAs the heart stops beating, the body’s cells are deprived of oxygen and pH changes occur. Cells gradually lose their structural integrity and begin to break down, releasing cellular enzymes which break down cells and tissues in a process known as autolysis, degraded by the body’s own enzymes.
