Thermodynamics Aspects in Biological Systems The human body processes a lot of energy daily. The energy processed is usually measured in calories for the human body. A calorie is an amount of heat energy needed to raise one gram of water by one degree Celsius. The human being will usually intake two thousand calories a day. Because of the laws of thermodynamics, the energy received by food must be burned. The human body burns a lot of these calories by itself. The way that the human body burns these calories is through a process called metabolism. Metabolism is the way that the human body will turn food into energy. This energy is needed for the human to survive. The energy will keep the body at a stable temperature. The biggest factor of energy is when the body uses it to rebuild cells and body tissues. Energy is needed for muscle use as well as mental energy. There can be excess energy which the body will need later. Another way the body will use up energy is the thermal transfer of heat from the difference between the body temperature and the environment temperature. When there is an overabundance of calories, the body stores it as fat, which usually means weight gain.
