While the digestive system does provide nutrients and fuel for muscles, it is not directly necessary for the functioning of the muscular system. Muscles are able to contract and create movement without the digestive system, although they may not have optimal energy and nutrients without it. The respiratory and circulatory systems provide oxygen and nutrients to the muscles, the nervous system controls muscle contractions, and the skeletal system provides structure and support for the muscles.
