tent. Explain the hiker’s heat gains and losses‚ and what mechanisms would come into effect to keep his temperature at the desired 37ºC. Humans are subject to vast changes in environmental temperatures‚ but our complex biochemical systems have a major limitation in that enzymes only operate within a relatively narrow temperature range. Accordingly the human body have anatomical and physiological mechanisms that keep body temperatures within acceptable limits‚ regardless of environmental conditions
