How is body temperature regulated (General principles and specifics of thermoregulation) How is body temperature regulated?
Generally speaking, under normal conditions the body temperature of the internal organs varies between 36.5 and 37.5 C, whereas at a cutaneous level it varies between 32 and 28 C, and it is obviously much influenced by the ambient temperature. Again under normal conditions, the blood supply to the muscles is scant, whereas the values of cutaneous blood supply are average. Sweating involves the dispersal of 25-35 ml per hour (perspiratio insensibilis), the cardiac rate varies between 65 and 75 beats per minute, ventilation (meaning the volume breathed per minute) is approximately 7-10 liters of air per minute and the thermal balance (production and loss of heat) is perfectly stable. Under normal conditions, internal temperature can vary by about 1 degree centigrade, between 36.1 and 37.5, unless the following conditions apply: fever, extreme climatic conditions, prolonged immersion in hot or cold water, intensive and prolonged physical exercise Man, as an organism, can be likened to a m
