Thermoregulation Mechanism in the Human Body

Previous studies have not considered the temperature control mechanisms of human body when a conflicting information is received from peripheral and central thermoreceptors. Our experiment was designed to investigate how the thermoregulation mechanism was activated when there was a passive heating to the human body and to find out how the body would react to the situation when the human was experiencing the heating and cooling simultaneously. Our first hypothesis was accepted, where the body regulated cutaneous vasodilation to enhance heat loss through sweat evaporation and all the respiratory parameters were increased in order to supply the higher demand of oxygen. However, the second hypothesis was rejected, as the peripheral control had more influence than central control when the body received increased temperature to the leg and decreased temperature at the same time. Heating period The results have clearly demonstrated that during the heating period, there was a decrease in skin resistance and total peripheral resistance (TPR) alongside an increase in heart rate (HR), cardiac output (CO) and peripheral skin temperature, as compared to the relatively stable core and oral temperature, shown in figures 6, 7, 9 and 12. The metabolic rate and respiratory parameters (Respiratory rate, oxygen consumption, tidal volume and minute ventilation) were also increased as seen in figures 1, 2, 3, 4 and 5. A significant decrease in respiratory rate and minute ventilation at 30 min of
