BMR = 1781.32474 Kcal/day

You need to use your metabolic rate in Walls as calculated early (MR, or heat energy production and transfer). You are on holiday in a tropical paradise. On a typical day your rectal temperature is 37 degree C and your mean skin temperature is 33 degree C. Suddenly, a malaria attack develops with a 7-fold rise in MR, and then you reach a temperature plateau of 40 degree C, with a mean skin temperature of 34 degree C. The conductance of the shell (C_Shell) is a measure of skin blood flow. This can be calculated by the formula: C_shell = MR/(T_core - T_shell). Calculate the conductance of the shell at rest. Calculate the conductance of the shell at the fever plateau. How does the body accomplish this increase?

Solution

BMR= 1781.32474Kcal/day

1 Kcal/day= 0.04842 Watts

1781.32474 Kcal/ day= 86.25174 watts

1. Conductance of the shell at rest

C_Shell = MR/(T_core- T_shell)

= 86.25174/(37-33)

= 86.25174/4

= 21.5629 W/^oC

2. Conductance of the shell at the fever plateau

C_shell= 86.2517x7/(40-34)

= 603.76/ 6

= 100.6 watt/^oC

3. Basal metabolic rate is a number of colories consumed for energy when our body at rest. When increae in the metabolic rate the body losses its weight because it will use more calories.So it may losses its weight.
