I know that All organ systems work together. First of all you need energy, digestive system does that. Then the circulatory system takes the food and takes it to the body. And for cellular respiration you need oxygen, so respiratory does that. And nervous is for telling and thinking what to do. And the main ones are skeletal and muscular systems. Muscular move bones which are from the skeletal system.
