objective 2.77 a

objective 2.77 a - understand that homeostasis is the maintenance of a constant internal environment and that body water content and body temperature are both examples of homeostasis
homeo- same
stasis- fixed point/conditions
so homeostasis - same conditions, conditions kept same/ constant
homeothermic- maintain same temperature
mammals, when the environmental temperature increases and decreases the body temperature remains the SAME (known as warm blooded animals)
they are homeothermic. they carry out thermoregulation which is an example of homeostasis
for enzyme reactions to occur at their maximum potential they have an 'optimum temperature'
the temperature that mammals maintain is very close to/same as the optimum temperature of enzymes
