Answer:
Homeostasis refers to the state of stable internal conditions maintained by the living species. Both the circulatory system and the muscular system functions together in order to sustain homeostasis. The muscular system comprises skeletal, smooth, and cardiac muscles.
The circulatory system assists in conducting the oxygen towards the muscles, which further helps in the process of cellular respiration. This cellular respiration gives muscles a suitable concentration of energy for the muscles to function efficiently and support the demand of the body. Thus, the circulatory system works in coordination with muscular system to maintain homeostasis.
