Answer:
Body temperature is regulated by the cardiovascular, integumentary, respiratory and muscular systems.
Step-by-step explanation:
Temperature is a quantity that reflects the amount of heat in something. Body, in turn, relates to what is related to the body (something with restricted extension or the set of organs, devices and systems that make up living things). Body temperature, therefore, is that which results from the balance between the heat produced and the heat spent by the body. This temperature is extremely important for maintaining the body's homeostatic balance and for this reason the body temperature should be adjusted so that it stays constant for as long as possible.
Some body systems act in concert to maintain body temperature regulation. These systems are: cardiovascular, integumentary, respiratory and muscular.
