Study Notes
Thermodynamics and the Human Body
- The first law of thermodynamics is an application of the law of energy conservation.
- The total heat produced by all the chemical reactions and mechanical work of the body is called metabolic heat.
- Metabolic rate can be altered by factors such as hormones, nutrition, and environmental temperature.
- Heat is added to the body from the internal energy consumption of fuel molecules through cellular respiration.
- Thermal energy in the process of being added to, or removed from, a substance or transferred from one material to another is represented by heat (Q).
- The indicator of the amount of heat contained in a system and in the human body is temperature.
- The ideal core temperature is considered to be located in the abdominal cavity, near the liver.
- When body temperature rises, the enzyme catalyst and chemical reactions are affected, as enzymes have optimal temperature ranges for activity.
- The normal temperature range for the body core regions is between 36.5°C and 37.5°C.
- The heat capacity, C, of a particular sample is defined as the amount of heat energy required to raise the temperature of the sample by 1°C.
