| Thermal Equilibrium | All objects in an area become the same temp. |
| Metabolism | All the chemical reactions that produce energy and heat in your body. |
| Every cell in your body (skin,bone,liver,kidney,vein) | This is where heat is produced in you. |
| Evaporation. | A process that needs heat to work. |
| Heat Radiation | Transfers heat across space. |
| Red skin. | Caused by capillaries dilating. |
| Heat conduction. | Happens when two objects touch. |
| Convection currents | Fluids move heat this way. |
| Hot sweat. | Only cools when it evaporates. |
| Normal body temp in the core. | 37degrees Celcius/ 98.6 Fahrenheit |
| Recovery time. | How long it takes for the body to return to normal after some stress. |
| Warm blooded animals. | Make and lose heat to keep temp steady. |
| Cold blooded animals. | Rely on surroundings to keep temp steady. |
| Radiation, convection, conduction. | Ways to transfer heat from place to place. |
| Heat radiation, sweat evaporating, red skin | Ways the body cools itself. |
| Metals. | Great conductors of heat. |
| Air. | Poor conductor of heat. (an insulator) |
| Water. | Conducts heat 25 times faster than air. |
| Insulator. | A material is a bad conductor of heat. |
| Cold. | The absence of heat energy. |
| Mitochondria | Cell structures where heat is made. |
| Hypothermia | The body's core temp drops a few degrees. |
| Food and Oxygen | Needed to make heat in the cells. |
| ATP, CO2 and H2O | New products made when the body burns food. |
