- Maintaining body temperature
- Sensing temperature
- maintaining a constant temperature requires absorption of heat from the environment and losing your body heat.
- Sensors are receptors
- sensory organs include:
- eyes
- nose
- skin
- Ear
- tongue
- send impulses to the brain which send messages to the effector.
- sensory organs include:
- Coping with high and low temperatures
- humans are most efficient at 37 celcius
- exercise causes respiration releasing energy causing heat energy
- sweat evaporates taking the heat energy
- humans are most efficient at 37 celcius
- exercise causes respiration releasing energy causing heat energy
- sweat evaporates taking the heat energy
- sweat evaporates taking the heat energy
- body shivers
- the movement of muscle speeds up cell respiration heating the body
- the movement of muscle speeds up cell respiration heating the body

- exercise causes respiration releasing energy causing heat energy
- Vasodilation
- when body is hot
- more blood flow to the surface causing a loss of heat
- Vasoconstriction
- when body is cold
- reduces flow of blood to surface reducing the amount of heat lost
- effectors act antagonistically
- humans are most efficient at 37 celcius
