Hypothalamus - The body’s thermostat (i.e. controls our body temperature), Blood - One of the body’s receptors that detects changes in body, Conduction - Involves the direct transfer of heat from one object to another , Water - __________ conducts heat away from the body approximately 25 times more quickly than air , Convection - The transfer of heat from one place to another by the movement of fluids and air molecules. , Radiation - Heat is lost (via electromagnetic waves) to cooler objects in the environment, such as the floor, walls, trees, and so on.  , Evaporation - Heat is transferred continually to the environment as sweat _________ from the skin surfaces and produces a cooling effect.  , Hypothermia - A decrease in core temp less than 35°C  , Hyperthermia - An increase in core temp greater than 40°C , Cramp - Muscle spasms caused by heavy sweating. Painful, but does not leave permanent damage. , Piloerection - A fancy term for Goose Bumps , Shivering - A person will experience a rapid involuntary cycle of contraction and relaxation of skeletal muscles, which is called_________.  , Thermogenesis - An ↑ metabolic rate (brought about by an ↑ release of the hormones thyroxin and adrenaline) will generate body heat. This process is called non-shivering______________. , Frostbite - Occurs when a part of the body becomes extremely cold, thus significantly¯’s blood supply to the area, which results in the body tissue freezing., Non-shivering - A type of shivering that doesn't involve muscle contractions., Dehydration  - Excessive water loss. When water output exceeds intake, the body has a negative fluid balance., Plasma - Made up of 90% h20) 7 contributes towards dehydration & decrease in performance.  , Homeostasis - The body's ability to regulate and maintain a stable internal environment of 37 degrees, despite external fluctuations. ​, Fainting - A symptom of dehydration , anaerobic - The heat has no effect on this type of exercise ,
